Spotted several nice things... A cool Akro -ade of some sort, some nice MKs and quite a bunch of lovely All-Reds
(I like All-Reds, I think they look like candy)
Ok, just gotta let me cook:
1. Load solid shot ammo in a tank
2. Put a marble in the barrel (a toebreaker), right in front of the round
3. Fire
4. Profit
