“Firefall” is a free-to-play, massively multiplayer online, third-person shooter game. With jetpacks. If you aren’t already sold by the mention of jetpacks, consider the talent behind the game’s developers, Red 5 Studios. The company was founded by Mark Kern, team leader for “World of Warcraft.

I’ll shamefully admit that I don’t have much experience with the “Tribes” franchise. I bought “Tribes 2” when I was younger, yet I was so frightened by the complex ESDF control scheme that I never got around to playing it much.
