Homepage: Tremulous

The biggest RTS element in the game is the ability to build structures with a wide variety of functions such as healing, respawning and defense. This feature enables more strategy than just running around and shooting at the opposing team. Another big difference in this game is the two races: humans and aliens. Aliens are more fun to play than the humans due to the ability to climb ceilings and evolve into other classes as they rack up kills. All in all, Tremulous is a must for any gamer looking for a deeper online shooter that is free to play.
