Yeah warframe is similar. It has changed a lot since 2014 and is adding an open world map like Destiny in the next few weeks.So they are trying to be Destiny-like now?
Don't take me wrong... at launch I played over 500 hours of Warframe on my PS4 until Destiny.... it at time aren't similar.... I really enjoyed Warframe (there are some weird battle minigame that you need to create a bridge in your clan to fight others when I left).
