Alien Eggs are an enemy introduced in Duke Nukem Advance.
It looks somewhat similar to a protozoid slimer egg, except it's brownish and it's assumed the egg's are of the Alien Crabs. A tentacle, or something that appears to be the infant Alien Crab is sticking out, so it can spit green acid at Duke. The green acid could be seen on the top of this limb above the egg.
The enemy is similar to a stationary turret with limited range and can be dealt with from a distance. They are quite brittle and don't take much punishment. When Duke get's close enough the Alien Egg will fire acid at him.
- Though players would inevitably compare these egg's to Protozoid Slimer egg's, in terms of combat this enemy is more akin to the turret from Duke Nukem 3D.
