Warframe is going to be a free to play online game that focuses on co-op gameplay. This is a relatively new genre for free to play to tackle. So, it’ll be interesting to see where it goes. Though, when space ninjas are involved, I can’t imagine any outcome other than success.
If Warframe looks familiar, that’s because it’s the game Digital Extremes, the developers of Dark Sector, wanted to make as opposed to what hey actually made with Dark Sectors. Here’s a trailer of what Dark Sector was originally going to look like.
