Waiting on PSO2, tired of World of Warcraft, Mechwarrior Online's experience has stagnated, then my friend showed me Warframe.

Heard of it in the past year, didn't pay attention to it, didn't expect much of that free-to-play... but man is that quick gratuitous action! Takes a while to get used to all the 'parkour/actions' you can end up combining (I'm still getting the hang of ducking in mid-jump then shoot then kick someone before landing), but it's such a good mix of Vanquished and Ninja Gaiden, looks great too and fun co-op. Besides, once you know the basics, you can survive easy, most of the fancy stuff is for show, while some of it does have its use.

If you're into it, look me up! It's BWS-1 in that game as well.
