If you haven't bought the game, you can find a more up-to-date version at 4minutewarning.itch.io/ravager. If you're looking for the most recent release, you'll need to subscribe on SubStar, link your account to Discord (the invite to which is found on 4MW's SubStar), and find the download link in #game-builds. If you're not up for subscribing, the Discord server is still a great place to receive news about the current situation and changes to the game.
