Soldier Front 2 is a first-person shooter that features all of this. If you’re interested in a free-to-play MMOFPS with a slight science fiction approach, you might want to check out the game. Publishers Aeria Games have announced that the sci-fi shooter has gone into closed beta, but not just any kind of closed beta. For this phase of testing, players won’t need keys to play the game.
