Solar Flare is a single mission, originally going to be a small campaign meant to mimic the pre-2000s FPS games like Half-Life in terms of look and feel.

You are Zulu 1, the leader of fireteam Zulu, a Spartan III commando team. Take part in the Siege of Paris IV with pre-2000s art-style and classic-esque game-play.

Set in the Project Daybreak fan timeline of the Halo Universe.
