Discount Mayonnaise is a fast-paced run-and-gun platformer. Fight your way through a cave full of weapon-wielding maniacs as a giant worm pursues you. Avoid becoming worm food and stay away from the bubbling yellow liquid as you run to the bunker at the end of each stage. Collect power-ups and coins that are scattered throughout the levels. Buy new weapons and clothing in shops at the beginning of some stages.
