Last year's downloadable dual stick shooter All Zombies Must Die! has risen to Steam with its definite version, which purports to fix several of the game's previous issues. Now you can get it at 20% for a limited time, placing the game at a very cool $7.99.

"Zombie swarming" and repetitive missions have been fixed in this "definitive version," say the devs in a press release, and as we've said before, it's nice when studios listen to feedback from their fans. Maybe Bioware could take a lesson.
