This excavation team's bitten off more than it can chew and now it has some mummy danger to swallow! Throw serum grenades at the mummies to transform them back into humans. Grenades have a recharge time, so shoot the mummies to fend them off while you wait. If a mummy grabs you, alternate between the right and left arrows rapidly to free yourself from his grip. Cure all of the mummified workers in a room to progress through the pyramid.
Arrows = Move, Z = Shoot, X = Throw Serum Grenade.
