This game has a lot of humor in it. The characters crack a lot of jokes about how they feel like they're playing a video game, or about the "kill quests" to move on to the next level and what not.
Naturally, the story is lacking, and the game play is kinda stale. I played far enough into it to get a taste of the rpg elements in the hopes that I might be pulled back in, but it couldn't keep my interest for long. I wish I could say I finished this game, but that never happened.
You are forced to play as certain characters from time to time, helping to move the story along. This wouldn't be a big deal if the characters were balanced. I'm sure this game can be a lot of fun with other players, but it's local co-op only which is always a bummer. There are far better above head shooters on steam.
