Was really fun to play at it's peak, after a while hackers started to infest the lobbies. I hated how you can only rent weapons as a free to play like many shooters at the time like Crossfire and Combat Arms. I remember having friends that would hack in skill perks for their HP and SP to be higher than normal. Sadly, the game shut down but there's private servers like S4 Remnants that are still up. The gameplay in this game is really one of a kind, learning how to wall jump and excel in movement is a priority in this game. Give the soundtrack a listen, I promise you'll like it.
