Cronus Zens
How a 2K27 auto green Zen script times your shot
An auto green script takes the release off your hands. You press the shot button once, and the Cronus Zen holds the shot for a set number of milliseconds and lets go, so the release lands at the same moment every time. That number is the green window. This page explains the window, tempo, calibration and ping using cronus2K, our own NBA 2K27 script, as the worked example, because its code is the one we can describe exactly. Then it lists the scripts in our catalogue whose descriptions say they time the release.
Watch: calibration and auto green, step by step
What’s in the video
What auto green means on a Zen
A Zen script is a small program that runs on the Cronus Zen, between your controller and the console. It can press, hold, time or repeat inputs, and that is all it does. There is no AI in a Zen script and it doesn't watch the screen: the Zen runs offline and only knows what your controller sends it. When the hold matches your jumper's release the shot greens, and when it doesn't, the shot is early or late.
Two kinds of shot get called auto green. In a timed shot the script decides the release: it holds Square, or holds the right stick down, for the number of milliseconds you set, then lets go. In a tempo shot you still decide the release: holding Square holds the right stick down, and letting go makes the script flick the stick up at a fixed speed. A tempo shot makes the stick motion repeatable, but only a timed shot takes the timing off you. The list further down separates the two using each script's own description.
The green window
In cronus2K's default Shot Style, BUTTON, you press the shot button and cronus2K holds Square for the Green Window. How long you press doesn't matter. The default is 550 ms on the GUARD build, 518 on WING and 550 on BIG, adjustable from 10 to 1500 ms, and each build keeps its own number. This is the number that decides early or late: if the shot comes out early, raise it, and if it comes out late, lower it.
The window doesn't start the moment you press. A standing shot begins with a very short right stick tap and a pause, so Square goes down about 0.16 seconds after the press once your left stick has been still for 1.25 seconds, or about 0.18 seconds before that. A moving shot with Quick Stop on stops you first, and Square starts about 0.32 seconds after the press. These lead-ins are fixed, which is what lets the same window repeat.
When you program cronus2K on the cronus2K page, the Your height slider sets a starting BUTTON window: 628 ms at 5'7" plus 8 ms per inch, up to 788 ms at 7'3", so 6'4" starts at 700. It is a starting point, not a finished number, and calibration finds the rest.
Tempo: the stick half of the shot
Shooting on the right stick adds a second number. In cronus2K's RHYTHM style the script holds the right stick down for its own RHYTHM Green Window, 600 ms by default, then flicks it up over the Tempo, 98 ms by default and adjustable from 5 to 200. In HOLD you hold the shot button and let go yourself, and cronus2K flicks the stick at the Tempo when you release. Both need NBA 2K27 set to rhythm shooting on the right stick, because Square never reaches the game in those styles.
17 of the 26 NBA 2K27 scripts with a description in our catalogue mention a tempo setting, usually called Tempo Speed, for the part of the shot where the stick travels up.
Tempo is calibrated as well. In RHYTHM, after an early, late or OK answer, cronus2K asks about the flick: FAST lengthens the Tempo, SLOW shortens it, and GOOD leaves it. In HOLD, where you choose the release, calibration tunes the Tempo only.
Calibration
Calibration is how cronus2K finds your window instead of you guessing it. Start it from Calibrate on the Shoot page. Take a normal shot, then answer on the D-pad from what 2K showed: Up for green, Left for early, Right for late, and Down for a shot that was timed right but didn't green, such as a contested one. Early raises the window and late lowers it.
The first change is 40 ms. Each time your answers switch direction the step shrinks to two thirds, never below 4 ms, and it is capped by how many greens you have so far. After 10 greens it saves the window for the build you are on, so calibrate each build you use. Calibration shots have no random variation: at the same number, every calibration shot is held for exactly the same time.
The routine we give cronus2K owners: go to MyCOURT offline with Ping at 0, pick one spot such as the three point line, and use the jumper you actually play with. Stand still for about 2 seconds before each shot, so every shot is the same standing shot, and answer with exactly what 2K showed. Calibrate fades separately on the Fade page.
Calibration isn't only in cronus2K. In our catalogue, Green and luraNBA also describe a calibrate mode.
Ping and online delay
Online play adds a delay that offline play doesn't, so a window that greens in MyCOURT can be early online. cronus2K handles this with Ping, on its System page: extra milliseconds, from 0 to 300, added to every Green Window, Fade Window and free throw window when you shoot. It isn't your internet ping. It is an offset you find by testing.
Calibrate with Ping at 0, so the saved window stays your offline base. Then play online and raise Ping a few ms at a time until you green, then a little more so you sit in the middle of the window rather than on its edge. Don't add your ping to the Green Window by hand. Modes can feel different, such as the park, rec, theater and Proving Grounds, and some players keep a different Ping for each. A wired Ethernet connection helps.
For small fixes during real games, cronus2K's Quick Tune, off until you turn it on in the System page, nudges the window the last shot used by 5 ms: hold L2 and press D-pad Up if you were early, or D-pad Down if you were late. It saves at once and shows the new value on the Zen's screen for a second.
Other scripts have a similar offset under their own name: SLEM describes a latency or ping setting.
Why no script greens every shot
No Zen script greens 100% of shots, ours included. The Zen presses buttons at set times, and several things move the target:
- A contested or heavy shot won't green whatever the timing.
- Standing and moving shots are different shots in 2K, but cronus2K has one Green Window for both, so a number that is right standing can be early or late on the move.
- Online delay changes from game to game and from mode to mode.
- Outside calibration, cronus2K holds each scripted shot about 1 ms shorter to 3 ms longer than the menu number, picked at random per shot, so a window right on the edge of the green can green in calibration and sometimes miss in games.
- Changing your jumper, release speed or visual cue changes the timing, so calibrate again after any of them.
Our own guidance for cronus2K is that a consistent jumper from similar spots gets most people to around 80% with tuning. A script sold as AI is marketing: the Zen runs offline and only presses buttons.
Scripts in our catalogue that time the release
These NBA 2K27 scripts say in their own descriptions that they time the release for you. The line beside each is quoted from its description, and the script's page has the rest.
| Script | Access | From its description |
|---|---|---|
| Aboki Premium | Free | R3 (RS) fires an Insta Shot, holding the stick down for Insta Speed (500 ms, 100 to 1000), 30 ms longer while moving and 20 ms shorter off the dribble, then flicking it up. |
| Burger | Free | Press R3 (RS click) for Insta Shot: the stick holds down for Insta Speed (605 ms, 100 to 1000), gathers for Insta Tempo (49 ms, 0 to 300), then snaps up. |
| Fanta Auto Green | Free | R3 (RS click on Xbox) is Insta Shot and runs the whole shot from one press, as a Turbo Fade with R2 held. |
| Glock's Remake Cold Fent | Free | Press R3 (RS on Xbox) and it holds Square (X on Xbox) for your Normal time. |
| Glock's Script | Free | Auto Green instead holds a tapped Square 465 ms, 678 ms with R2 held, or 450 ms for Catch & Shoot on L1 (LB). |
| I Pull Reds | Free | Tap R3 (RS click on Xbox) for an Insta Shot that runs the whole shot from one press, or hold R2 with it for a fade version. |
| KB | Free | With R3 Auto on, one press of R3 (RS click) runs a whole timed shot. |
| Margielq | Free | Press R3 (RS click on Xbox) for an Insta Shot: the script runs the whole shot by itself, holding the stick down for 590 ms before the release. |
| Panda | Free | Tap your shoot button, Square (X on Xbox) or R3 (RS) if you pick it in the menu, and the script holds Square (X) for a set time and then lets go, so every shot gets the same hold. |

| Slade's Secret | Free | In Timing mode, tap R3 (RS click on Xbox) to hold Square (X) for Timing MS, 500 ms by default (100 to 1500). |
| SLEM | Free | Green holds the shot button for Stand 700 ms or Fade 850 ms, with separate Move and Fade times for each side in Smart mode. |
| Zen Abuser | Free | R3 (RS click) is the Insta Shot, a stick shot with its own timing that also reverses when R2 is held. |
| Dime | Club | Auto Green fires on R3 (RS click on Xbox) and holds Square (X on Xbox) for your Jump Shot Hold time, 610 ms by default. |
| Green | Club | Press R3 (RS on Xbox) for a standing auto green: it holds the right stick down for Auto Green Timing (666 ms by default), then sweeps it up. |
| luraNBA | Club | With Auto Green on, click R3 (RS click on Xbox) and it plays a right stick rhythm shot timed by Auto Green Timing, 666 ms by default. |
| Panda Green | Club | Tap Square (X on Xbox) and it holds the shot for your Button Shot time, 552 ms by default, then lets go. |
| Prime | Club | AI Auto Green shoots from one click of R3 (RS), holding the stick down for the Auto Green MS time (550 to 746 ms, 682 by default) before the same flick. |
| Saint | Club | R3 (RS) runs Insta Shot, a timed right stick hold set by AutoGreen Speed (100 to 1000 ms) and AutoGreen Tempo (0 to 150 ms), and Turbo Fades, a longer hold (AG Fade Speed, default 1500 ms). |
| TT Scripture | Club | R3 (RS click) runs a one-press Insta Shot, reversed with R2 held, while L3 (LS click) is a plain Square. |
Glock's Remake Gods Menu, MDM, MyDunk, MyQuick-Stop, MyRhythm, yew2K and YOGA Bibal are in the catalogue too, but their descriptions don't say the script times the release, so check each page for what it does.
cronus2K isn't in the table because it has its own page. It times the release in its BUTTON and RHYTHM styles, calibrates, and has Ping and Quick Tune, all on cronus2K. The free ones are compared in free NBA 2K27 Zen scripts.
Auto green and bans
On 24 September 2026, 2K said it had given its first wave of permanent bans to NBA 2K27 accounts that used cheats and scripts for shooting aids, going back to Early Access on 26 August 2026, with console or PC bans for repeat cheating. 2K didn't name the Cronus Zen, but an auto green script is a shooting aid.
No one, us included, can promise a script won't be detected, and nothing in a script's settings, Human Logic and the built-in variation included, is an anti-ban feature. Read can you get banned for using a Cronus Zen before you play online with one, and cycle the Zen to its logo screen to play with no script running.
Video transcript
Who this is for
0:00If you just got a Cronus Zen for 2K27, or your shots keep coming out early, this video is for you. I’m going to walk you through Cronus Zens 2K in the order you’d actually set it up: calibration first, then shooting, then the rest. At the end there’s some real in-game footage with the hand cam on. If you want to grab it, the link is down in the description. It’s a one-time purchase that works on all consoles, and you get lifetime updates, priority support and instant access to all of our guides.
Calibration first
0:35Let’s get into it. First up is calibration, because everything else depends on it. The script can’t see your screen. It sends the same timing on every shot, starting the moment you press. So go into Crew HQ and pick one animation, like a catch and shoot or a shot off the dribble with the ball in your hand. Calibrate on that, and use that same animation in your games. If you want it tighter, use the calibrate feature. Take shots, mark each miss as early or late, and keep going until you find the top of your green window. Then the script locks it there.
Auto green
1:17Now for auto green. Tap down on the right stick and the script takes a rhythm shot for you, so your green window is a lot bigger. It’s most consistent off standstill shots, dribble cancels and quick stops.
Button tempo and fades
1:33If you’d rather shoot off your buttons, turn on button tempo. Your normal button shot becomes a rhythm shot, so you get a bigger green window there too. It’s close to how 2K26 played, but without the white early shots. With it on, Square, or X on Xbox, does the rhythm shot. For a normal Square, use the button you set in the script. Both of those come with their own fade. The right stick fade runs off auto green, so you tap down on the right stick while you’re on the move. The button tempo fade comes off your button rhythm shot.
Quick stop
2:10Next is quick stop, which fixes the slide you get when you let go of your stick. With quick stop one, you tap L2 and shoot. With quick stop two, you let go and shoot. There’s also R3 quick stop, which stops you and takes an auto green shot in one press. That one has its own calibration.
Dunks
2:35For getting to the rim, there’s easy dunk. Hold L1, or whatever you remapped it to, while you drive, and it does a contact dunk. Turn on L1 easy if you want a timed dunk instead.
Dribble macros
2:48If the new dribble system has you lost, dribble macros can help. Tap a direction on the D-pad for a move, with down giving you a hop back, or hold it to chain a sequence. You can go straight from any of them into auto green or button tempo.
Stamina
3:07Infinite stamina keeps your stamina refilling, so you can keep sprinting. It only works at full sprint, so dribbling doesn’t count toward it.
System menu and price
3:17That’s over 20 features in total, plus three profiles to save your builds. In the system menu you’ll find hair triggers, overclock, and haptic shots, which buzz your controller when it’s time to let go. You can also change your Zen color there. Cronus Zens 2K is $55 one time, and code Halloween 10 gets you 10% off. There’s no monthly subscription. If you’ve got any questions, hit us up.
In-game footage
3:48Here’s some real in-game footage of Cronus Zens 2K.
cronus2K today: it is $64.99 once with lifetime updates, and Cronus Zens 2K and cz2K in the video are now called cronus2K. The full feature list is on the cronus2K page.
Auto green questions
What is the best green window for 2K27?
There is no single number. It depends on your jumper, your build and your connection, which is why cronus2K calibrates it and the other scripts let you set it. cronus2K starts at 550 ms on GUARD, 518 on WING and 550 on BIG, and the height slider on the cronus2K page gives a closer starting point.
Does an auto green Zen script work online?
Yes, but online delay moves the window. Calibrate offline with Ping at 0, then raise Ping a few milliseconds at a time in online games until you green.
Is auto green the same as a tempo shot?
No. Auto green times the release for you. A tempo shot only makes the stick flick the same way every time; you still choose when to let go.
Why does my shot green in calibration and miss in games?
Calibration shots are held for exactly the same time, while game shots get a few milliseconds of built-in variation, and game shots are often moving, contested or delayed online. A window sitting on the edge of the green shows it most, so move it towards the middle.
