Hey I had work! Anyway the game has a major glitch.
Basically if your sub-weapon collides with an enemy, it blows up and
does major damage to what it hit. The glitch is that the game actually
remembers the spot the weapon was destroyed, and this becomes an enemy
death trap. Any enemy that enters that space will be damaged. If you ram into
a boss just enough so your sub-weapon explodes (and you don't crash into it),
the boss will be constantly hit by the new dead zone. Stationary bosses go down
in mere seconds using this.
There's a vid on youtube showing it some place, too.
Couldn't find the original vid, so I made my own.
The glitch won't actually kill anything, but brings everything down to one hit.
Notice how the boss flashes, and I'm not even shooting. Then it only takes one
hit to kill it.
