Megalaser:
- it destroys all enemies and projectiles on contact (including the normally indestructable plasma projectiles)
- Its timer counts down constantly, but it counts down faster while using it, so it's important to
  conserve if there are no enemies on the screen.       <<<has been said many times elsewhere, but is pretty important>>>

T-63 Linstrad tank:
- do these always shoot in the same pattern?  (eg. medium, short, long, medium, short, ...?)
