FAQ :
(a lot of these get asked by 10 times every devlog so this saves me writing answers 18 billion times)
How Do I Get to the special levels?
Each special level can be accessed by its corresponding level, ie. M-1 can be accessed via 0-1, M-2 can be accessed via 0-2, etc. The exits to the special level are hidden somewhere in the standard level - Look for anything that seems out of the ordinary and you shouldn't have too much trouble finding it.
Once you unlock a special level, you can access it from the level select screen.
(you could also use the cheats page in the options menu to unlock the levels )
(or you could also hack your save file to unlock the level....)
Can you port this game to Mac/Linux/Android?
For Mac and Linux, I believe I'm required to have a Mac or Linux machine in order to make a build, which I do not have. I'll look into ways around this, so a Mac and Linux build may be possible in the future. As for Android, I have no intention of making a port to that platform.
Is this a virus? It's showing up as a virus on my PC?
No, it's a game. If you still think it's a virus even though there's videos of the dev process on YouTube then I guess don't download it. Most itch.io games are flagged by antivirus.
How was this game made / what was this made in?
The game was programmed in GameMaker Studio 2, with the art being made in the in-engine editor. Music was created in BeepBox (ost tracks), and FL Studio (non ost tracks).
What will the finished game be like?
As of Ver 1.0, the essential content for the game has been completed (all of Prelude, ie. the first 5 levels of ULTRAKILL). It was always the plan to only recreate Prelude, as recreating the entire game or an act would be too time consuming and not all that fun, especially since this is a non-monetized fangame.
I do not plan on making any more levels from ULTRAKILL but may add more content in future updates (0-S, Cybergrind and possibly M-3). These extra updates may include new enemies and weapons.
That being said, if you really really want more layers adapted afterwards, this project will be open source and free for anyone to pick up (though I admit the code is pretty messy).
Do I have to pay money (in the real world) to play this game???
NO. This is a fangame and if I charged money for it I'd get ultrakilled.
What are you going to do after this?
Make my own game. I've had a few ideas for a while and think I'm almost ready for a full fledged game. I'll also start making devlogs and other videos on youtube, so if you'd like to stick around for that, or just support me, subscribe to my channel: https://www.youtube.com/channel/UC_RxqOgu0dYMfhEjPc_3g2A

could you either get this working on browser or chromebook pls
Hey guys I like this game really but i've got an issue...
if i kill the swordsmachiene in 0-2 is the challenge not completed. is there an other secret boss or is that a code problem
is it possible to get this running on a browser?
hello, i would like to resprite and continue this project. is it possible for you to give me the .yyp file?
my screen went green and made a buzzing sound for a second before my pc restarted without warning
10/10 demake very well made
(ps. there is a stray black pixel on the left side of the itch page of this game)
turret knight is basically impossible because parrying doesnt regen health like base game.. his attacks literally disintegrate your hp and it takes the force of 10 suns to heal one hp from him so you're just stuck with 12 hp and die
im begging you make parrying regen health for my sanity
looks like brain rot pvz mods have given people skill isues
stuck on the menu screen, can't press any of the buttons, are you supposed to use mouse bc it aint workin
This is a bug with controller input, Mouse cursor won't appear if you have any controllers plugged in, so make sure to unplug any controllers while on the menu.
Doesn't let me open the game anymore.
EDIT: the new version 0.31 fixes this issue and is available above.
I'll work on fixing this for next patch, if you want to fix this now you could go to localappdata find RETROKILL folder and delete the options file - that should fix this issue.
There is a little thing that i see in 0-1 but i can't enter it :(
how do you get to m-1 and m-2 i dont get it
Imagine if you could play the full game if you insert the .exe into the game to prove that you own the full game
holy shit
sonic.exe ass place
SONIC.EXE?! LIKE, AS IN, ULTRAKILL.EXE DOWNLOADABLE ON STEAM?!
WHAT!?!?!?
I need help, every time i try to open the game the window appears to be too small, and I'm unable to open the settings or hit the play button. I have tried installing the game both through ZIP and EXE but the result is the same. How can i fix this?
Id try ALT+ENTER to try change the screen size, otherwise I'll work on fixing this for next release!
same issue but cant select anything
As of the most recent update (1.0) this problem should be fixed. You can toggle fullscreen with F12, or just change the screen size manually.

The game is good but the Turret Knight is really hard especially to new players and i play the original game and beated every level and it was more easy to complete that the Turret Knight
Good concept bad executation
i beat the game multiple times, p-ranked prelude and act 1, p-ranked P-1, and i still got my ass handed to by turret knight
i think i have skill issue
nice
Can you make a mobile version? ;)
no, go fuck yourself and buy a computer
give us the right to use the nailgun
Why virustotal and windows security system says that there's a some trojan virus?
2 out of 62 anti-viruses think it's a virus.
Pretty sure that's a false positive.
Alright, thanks!
give linux build
just use wine, dawg
works perfectly fine for me
i like this death screen :^)
windows says its a virus
It's a shame this was made in a different game engine, as a port to Ultrakill (as a secret level) would've been so cool!
i like the death screen :D
error following instructions, it says its more MB to download RETROKILL than RETROKILL
I have an error because of which v1 goes to the right side only
good :3
good :^)
This is a really fun take on Ultrakill, and I love the BGM! Movement is difficult and the range for getting blood is a little small, but it's looking good so far!
new ultrakill must die teaser looking great
The wall jump rly needs some improvement.
also, not sure if it is unity being a bad engine, but the turret thing seems like to slow down the game over time.
Hard damage is that feels like, something more strict that violent, which when associated with projectiles not properly disappearing after respawn, the whole game screams me to get rekt.
Also, if you intended to make some bullet hell thing, please add some invincibility frames after damage. dat minigun and white beam is a frickin instakill.
besides that, overall gud
the demos based on gamemaker not unity
Same
:D
Mostly really good tho I have some feedback (warning long and nitpicky)
-HP and Stamina are hard to see at a glance, need options for crosshair hud and/or a version of the main hud with the meters instead of numbers
-Needs sound effects for weapon swapping and shotgun reloading, and a clearer/more noticable sound for taking damage. I found it harder to keep track of what was happening bc of the sounds not being as clear as main game IMO
-The punch always being horizontally in front of you feels wrong, IMO it should be directional like the weapons
-Projectile boost timing is weird, the punch hitbox seem to last longer (+ maybe take longer to come out?) so the easiest way to proj boost is by punching before you shoot which is backwards. Plus it seems like the game randomly chooses which projectile is boosted, whereas in the original game it's always the central projectile that goes exactly where you crosshair is
-When you hold Ctrl to do a shockwave ground pound you immediately start sliding when you hit the ground, which really messed up my muscle memory, should work like main game
- It took me way too long to realise the secret boss was parrying my parrys back, I think the animation and sound for that should maybe be clearer? Not sure how to do that though
-Shotgun parry needs to show up in style feed (and I'm not sure it works on enemies other than Maurice? That might just be my incompetence tho)
-You can farm style by punching dead Maurices
-When you respawn sometimes you immediately shoot or dash (based on the button you were holding/pressing when you died, I think?) Which can be pretty bad with Core Eject :P
Additional suggestions
-Explosions should redirect projectiles for +FRIENDLY FIRE shenanigans
-The weapon freshness system and reduction of hard damage on higher style ranks would be cool
-This really isn't necessary but the stats thing that shows up when you double press tab would be a nice addition
-add funy maurice leggies
P.S. Is the secret boss a reference to something? The dialogue about being from another dimension makes me think it's a character from another game but
idk who it isEDIT: just noticed them in Shotgun Spire trailer, i seeP.P.S. also just wanted to add my favourite part of the secret boss fight was that they stop being able to parry your parries once they start duel wielding, put a smile on my face once I realised it. I generally seem to like bosses that start out with defensive capabilities then abandon them for aggression (sundowner from mgr, the hand from furi)
P.P.P.S. almost put "piercer beam should go through Maurices" before I remembered the standard piercer doesn't work like that lol, slabbrained
Loved the game, and "enjoyed" the secret boss =P Left a follow and I look forward to a complete version!!!!!! (may take a bit to upload upon post, slower internet)
This is really neat, I like what you're doing however I have some suggestions. Idk what the i frames are on dash but they do not seem correctly tuned for that last level. Additionally I feel, as inaccurate as this is (not that I imagine accuracy is all that important to you which I like) parry should have some i frames. My though process here is because there's so many projectiles going in so many directions and frankly not having that third dimension to dodge in really limits this kinda fight. If there were a few i frames when you parry however, don't you think the final level would be a bit more reasonable? So many projectiles come out in one burst and you can only parry one, and dodging out of parry doesn't seem to do the trick either. I've given my 2 cents, you've got some cool ideas here and I'm excited to see more. Also uhhh keybinds someday I beg of thee!
its really fun but there are some things i noticed:
sliding after a slam doesnt boost speed
dashes give momentum afterwards, even without jumping
holding ctrl after slamming starts a slide instead of making a shockwave
+ FIREWORKS is exploding an enemy midair, not just exploding them
this is still an amazing project tho
This was really fun, I played through it a few times and there are a few bugs involving the music and being able to skip the secret boss. I cant wait to see more though!
hi! i can't play this because the window starts out extremely small and the mouse can't exit the top left corner of the title screen, because it'll exit the game window entirely when i go too far. there's also seemingly no shortcut to get to fullscreen, which would probably fix this :c
As of the most recent update (1.0) this problem should be fixed. You can toggle fullscreen with F12, or just change the screen size manually.
this game is fantastic.
this is REALLY GOOD. movement is great, i like how it is inspired by ultrakill and not an exact recreation, the gunplay is very good, and the new boss is on the same quality and difficulty as a prime boss. nice job :)
