Saw this while browsing steam store, thought that it was so hilariously bad that it deserved a thread.
So what is revelations 2012 ? It's literally a reskin of left 4 dead 2 where instead of fighting zombies in various different environments, you blast demons with some shitty particle gun and you fight in mayan themed environments.
It literally copies everything from left 4 dead 2, it's menu, it's play style, most of the mechanics, crescendo events. It's not even a good copy, really let the screenshots do all the talking.
Also know what's the worst thing ? It's available on steam AND IT COSTS 20 DOLLARS.
