A more usefull bug in Robotron appears during the 'hulk/tank' wave:
You can force the tank robotrons to, in effect, run out of shots. The
best way to accomplish this is to blast all but one tank and just let it
keep firing at you, BUT DO NOT "SHOOT" IT'S SHOTS. After about 20 of it's
shots have bounced and dissappeared it will fire no more.. effectively,
it's out of ammo.
This is a great trick when you've been at it for a few hours and need to
use the restroom, take a smoke break or whatever... The hulk robotrons
roaming around aren't that hard avoid and anyone can do it (My *mom* did
it for me once when I used the can!)
