Savage: The Battle For Newerth.

The first of its kind: an online RTSS (Real Time Strategy Shooter). One player on each team was elected as a commander by the other players and played an RTS style game where he ordered units to build things and attack other areas. The rest of the players played in the world in an FPS/TPM pov. The largest match I was a part of had 128 players.

Unfortunately the company that made the game never really managed to recapture the spirit of the original and eventually they went bankrupt.

Pretty much nobody I knew even heard of it, let alone played it.
