This game is freaking Co-op Space Ninjas! AND IT'S FREE! FREE SPACE NINJAS! It's also only in Beta and already has more than 100 different missions! At the moment the whole play with your friends system is a bit wonky but it's still an amazing game. My advice would be to play Online with other people though because playing Solo is difficult and not nearly as fun.

Update 11/22/17
I'v recently gotten back in to this game and holy hell is there a lot to do. I will admit that it's a crazy grindfest but the movement and combat in the game are amazing.

Update 11/21/18
I still go back to Warframe pretty often. It's a great filler game for when you don't have enough time to start a story driven game and just want to mess around for a bit. The Fortuna update is HUGE and has added SO much to the game overall. I still HIGHLY recommend this game.
