Roam the streets of New York, imbued with unnatural jumping abilities, you can now disrupt the very fabric of society and collect pizza slices in the name of the glorious Rat King to summon the dark eldritch being of New York.

A build is one published version of the game's files on a branch. Steam assigns a new build ID every time the developer pushes an update, so this list is the update history of the app. The files inside a build (depot manifests) are only readable with an account that owns the game, which SteamRaw does not have yet, so build contents are not shown.

Firebug Games has been hard at work but to tide all yee' good people, we wanted to give you the news that the new update will be coming very soon, stay tuned! {STEAM_CLAN_IMAGE}/41410855/d076a4a807b501bb94b4a3b91518fd13cd44386f.png (Spooky city snippet above)
Hey everyone I'd like to address some concerns and update you all as to what's been happening over the last few months as we've been quiet for awhile now, first things first no we're not dead and neither is Rat Sim, we've been working hard behind the scenes on lots of new content, the main reason nothing has been released publicly recently is due to a file error a few months ago that resulted in the corruption of our city level, and until we get another one made we can't release any updates, we had hired a contractor to work on a new city level while the rest of the team focused on other side
Fixed fatal errors Fixed pause menu resume Fixed VR kit bug Fixed T-posing AI Fixed AI dying when walking into rat Fixed loading screen black screen issue Added proper game Icon Added bootup splash Fixed some other smaller stuff too that I forgot to write down ,_,

New Traffic System - Improved path finding, smoother driving/turning, and better player interactions/reactions. New AI system for pedestrians - Better path finding, high
After some time we are excited to announce a series of upcoming updates, starting with a massive overhaul which includes: Entirely New Map New Rat Model and Animations New Traffic and Pedestrian System Upcoming Features: The New York Deity Exterminators? Consumption of humans for the gaining of souls Now that the game is finally starting to look more like how we had originally envisioned, we are comfortable sharing it with the public. This includes attempts at increasing awareness of the game by hosting things such as the key giveaway/contest. Here's how to enter the giveaway: Contest lasts 24
