RF 

Red Faction, or RF, was one of the first great first person shooters that became HUGE on PC. Millions of people played casually in servers that featured wild 16 vs 16 mayhem, but many also joined clans to play competitively, typically in a 6v6 CTF style.

Weapons included assault rifles, shotguns, 20 bullet precision rifles that shot as fast as you could click, single shot snipers rifles, heavy machine guns, the default pistol, and rocket launchers.

The best unique feature in the game was that it had a destructible environment, meaning you could actually use rockets and c4 charges to blow holes in the walls and build tunnels across the map, letting you drop out of the ceiling onto the enemy flag.

.fa +PLuS+ -iCe- were some of the legendary clans that fought daily for bragging rights to call themselves the best.
