I began playing it a few weeks ago and its amazing.
There's a great and helpful community, and you can easily play online even with people you don't know because the game is built that way.
There's a lot of maps, guns, companions and frame to tryout giving the game great durability.
Strongly recommend.
If you want to give it a try use the link (https://www.warframe.com/signup?referrerId=59cf67353ade7f81ab249125) and you'll have an experience boost for 7 days. Its an amazing online game with great graphics and it's free. ;)
