Some game tips:
----------------------------
Blue planes drop extra missiles

Green planes drop +2 health for all Citadels; if a package lands on a Citadel it will repair more and put the fire out

Citadels lose strength at a regular rate but this is faster if they are on fire

----------------------------
Game Modes:
----------------------------
REGULAR - normal game game ends when all six Citadels are lost
