I wrote a RPG Scenario for the Gundam one year war setting called Gundam Blackbird. It's an hack of the excellent Lady Blackbird rpg scenario created by John Harper.
The scenario comes complete with rules, setting, a situation and characters ready to use. this is the premise:
Lieutenant Ivan Kovich and his MS Test Team, the "Blue Lightnings", have been charged with field testing a new federation Mobil Suit: the Gundam Blackbird.
However, while moving the Gundam Blackbird with Medea transport planes to no man's land, the Blue Lightning Test Team have been ambushed by Zeon forces. Cut from their main forces, the Team has been forced to crash
