Instead of tiberium or crystals or whatever, the resources in Meat Hell are meat. Meat harvesters drive around and collect huge chunks of meat and throw them in the back like a garbage truck. They take the meat to the butcher, where it is dissolved into pink slime, and distributed to the rest of the base by meat tubes, to be used for energy or to build new meat zombies, meat tanks or other units.

Generally meat chunks make it on to the map through a spurter. You can see these on the sides of this website! As long as you're on desktop. They squirt the fresh meat out from deep underground. But some meat units will also drop meat chunks when they die. You can recycle a swarm of meat zombies quite efficiently this way.

The meat is valuable in Meat Hell because it is fresh. So much of the surface is dead and decayed meat. Fresh meat can be hard to come by.
