Have you heard of Warframe? Well, you have now. The free-to-play co-op shooter is going into open beta this weekend. Lasting from Friday, February 15th at 12:00pm EST through Tuesday, February 19th until 9:00am EST, you’ll have your chance to slice, dice, and shoot all the aliens your heart desires. No beta key required. Even better, for allowing yourself to be a guinea pig, you’ll get access to an exclusive in-game weapon. Try it out, why don’tcha?
