It's pretty amazing. Great Devs. Constant weekly content updates and huge updates each 2 months. It also has great graphics.
Pros: 1. Great graphics 2. Great optimization (560 ti and it runs at 60 fps most of the time) 3. Multi-platform (Xbox One, PS4 and PC) 4. Huge amount of content (~41 Warframes, 280 other unique items) 5. Randomly generated map using tiles from specific tilesets 6. Great community 7. Devs that listen to players 8. Constant updates
A few downsides are that: 1. The game is difficult to understand as a new player 2. The game looks pay to win but it's actually the least pay 2 win f2p game. 3. There's grind but not as much as most MMOs.
