So about a year ago, I signed up for an alpha version of a game called Hawken. It is basically like the old game Mech Warrior from when we were kids. Its a mech based game where u run around shooting others or bots (in coop). Battles win experience which essentially allows you to buy upgrades in the form of a new gun from the basic, then there are deployable items in-game u can buy and "internals" which are passive effects applied to your mech. I've been playing it over the past couple of weeks and have enjoyed it. There are a few different types of "vs" game modes and one type of coop game mode vs bots. The game was free for me, though I am not sure if its free for everyone, or because I've signed up for the alpha and beta versions in the past. Here is a link to the steam web page: http://store.steampowered.com/app/271290/ I'll be curious to hear others thoughts.
