This game doesn´t have many competitors in the PS4. It´s a hack and slash 3rd person game that you can only play online co-op and counter at the same time. Until now it´s the best online experience that you can make many friends and also many enemies. This game has good graphics and high details with many weapons options, from spades to canons.
The good thing about the game is the search for new weaponry and new warframe armors. The bad thing is that the scenarios are very very repetitive just as the enemies, and soon or later you´re going to have to spend some money to buy more slots for items or new weapons.
Since it´s free and has good gameplay and graphics, it´s a MUST have game!!
