Psyonix's team-based competitive multiplayer game Nosgoth, which pits humans versus vampires, will be free to play this weekend. The game is currently in closed beta, but by buying a Founder's Pack you can gain access right now.
The free weekend begins Thursday, August 7 at 7 AM EST and ends Monday, August 11 at 3 AM EST.
Those who play during the free weekend will receive double experience points as well as an in-game badge. I wish this were a brand new Legacy of Kain game instead.
