Critters At War: Flies, Lies & Supplies is a standalone game in which you play in three theaters: Intelligence, Diplomacy, and Economics. Alternatively, you can mix this game with Critters At War and use any three theaters for a regular game or any five theaters for "epic mode".

Gameplay is the same in this standalone game as in Air, Land & Sea: Spies, Lies & Supplies, but with 100% critters and more vibrant colors.
