Colony Table: Back Alley
If you can get the ball speed just right (or if you're incredibly lucky), you can get the ball to catch in the back alley behind the Factory, and the game will award you with either a continue or an extra ball/shoot again, or invincibility during a bonus event.
Colony Table: Right Barricade
When pulling back the plunger on the Colony Table, go only as far back as the first two marks of the meter in order to catch the ball on the back of the barricade. If the barricade's light is still flashing (and it should be, if the ball doesn't pass it), all of the OUTPOST letters will be filled and start the sequence for a three-ball Multiball; just send a ball into the Tunnel, then the Cave, and the Tunnel again. Also, if you can time just right with the Right Flipper, you can bounce the ball off the corner of the barricade to get the ball bouncing almost continually between two of the Jet bumpers. This will effectively randomize the Bonus Event, upgrade to Super Jets, and score a lot of points for the Drain Bonus.
