Got an idea and would like to see it come to life? Say no more and write it down here. If good enough, it might make it into the addon.

Try to keep within the feel and aesthetic of Half-life 2's universe. Their colour schemes can't be too saturated such as a bright red, rather more natural themes and abilities such as a dark green-brown hide with the ability to plant biological sentries. Also try to state their role within the hive.

Ideas to start you off:
-A nurser/breeder type Antlion that remains within the hives its whole life. It tends the Grubs like a 'mother' of some sort and carries them around on it's bloated, bioluminescent abdomen. Evolved from ageing Antlion Workers that can no longer build tunnels and as a result of age become slower and less efficient at tunneling.
-An ambusher type Antlion that simply hides and waits for enemies to pass by, in which it unburrows, impales the prey and drags them down with them.
-A worm type Antlion. Workers that manage to not become a Nurser become the 'Trojans', massive worm-like beasts that can tunnel at extremely fast speeds and thus create networks that can easily transport troops to unguarded positions.
