WarHeads SE
 
 Gremlin fun:
 If you are playing the version with the Gremlin WarHeads
 present, find yourself a large planet to sit on, aim straight
 down at the planet's core, set your Power to 0, and fire a
 Gremlin - with it's multi-splitting tunneling behaviour you are
 quite likely to end up with well over 30 homing Warheads
 breaking the surface and buzzing about the screen - very
 impressive and fun!
