Unreal: FireStorm mod

Firestorm is a singleplayer mod for Unreal, following where the official expansion Return to Napali left off.

The player will take the role of prisoner 849 and return to the planet once again.

Return to new locales around the planet, including jungles, mountains, deserts, and floating sky islands, new unique locations not seen before in the original game.
Weild new weapons and items to aid you in your survival, and combat new enemies not seen before.
With both the Skaarj and the Marines returning you will combat both factions while trying to survive... and find a way home.

Firestorm makes extensive use of Oldunreal's unofficial 227 patch, it is recommended that players update their version of unreal to experience the most out of Firestorm.
