Welcome, Killbug, to the underbelly of the insect realm, where the skittering masses are caught in an endless battle for dominance.

You threatened them with your power. They clipped your wings and forced you into exile, but it was not enough to sate their hatred. A ravenous ambush awaits, and they want you dead.

Blade and barrel hungry for blood. Thirsty for the sweet nectar of revenge.

You will make them suffer, and from carapace to thorax, they will know pain.

As the Killbug, use your insectoid instincts to dash, double-jump and wall-run your way around the endless arena. Combine these fluid movement mechanics to reach enemies in all areas of this brutal battleground.

Slash and shoot your way through droves of ravenous beasts. From beetles to spiders to a giant larvae monster, there are endless swarms for you to butcher as the Killbug.

Become the master of death as you rise again and again, raining destruction on your foes and aiming for your next high score. Crush those bugs, over and over.


  • Battle a wide variety of savage insects in an endless arena.
  • Destroy hundreds of bugs in fast-paced, brutal combat.
  • Slash and shoot enemies with your blade and SMG.
  • Utilize aerial movement mechanics to double-jump, melee-dash, gun-hover and more, quickly adapting to combat different enemy attacks.
  • Sweat out a new high score on the global leaderboards, or compete to knock your friends off the top spot.


KILLBUG features various accessibility settings for players who experience motion sickness.

how do i download the game? when i click the download button it just takes me to the games steam page

We don't have a DRM Free build of the game. You should get a steam key when you purchased the game.

i never did usually when steam keys are included in games they show up in the download menu but there wasnt one there wasnt one on the email receipt either :(

Very strange, there's still plenty of keys left in the pool so if you can't find it I'd recommend asking itch support for help. 

Amazing game!!! Soo looks like Hyper Demon and Devil Daggers with UltraKill!!!! I waiting updates or next part!! we need more good Arena Shooters

ultrakill but bugs? yes. still good? yes.

Great Idea ! I hate bugs too much haha. I think the game is for bugs haters.  By the way, it reminds me unreal tournament game !


ultrakill moment

are leaderboards available? or are they  just a  steam version feature?

Steam only, that's why we can't provide DRM Free builds at this point. 

Thank you for sharing!

"Nothing is available for download yet."  Well, it does mention the Steam key right on the page so yes, that's on me I suppose...
