Overall reviews on the state of the game right now seem to be mostly positive, seemingly because the devs never gave up on the game and constantly updated and tweaked it. Shortest synopsis I saw was "Killing Floor with dinosaurs" and I know you folks love your KF.
It's on Steam sale for $0.49 for a single or $1.49 for a 4-pack. Figured I'd drop the info before the 250. (The game is normally $0.99 for a single or $2.99 for a 4-pack, but hey. Sale.)
