Unit ideas

[alexnakam]

Rebel Metrocop - It'll be slighty faster than the normal one, but will do less damage than the combine one.
Combine Chopper - should take as long to make as a strider, will do more damage than a strider but it'll be easier to destroy.
Advisor - It'll take around 5-6 minutes to spawn him, he'll be more powerful than a strider and hard to destroy, it's weakness will be RPG's or flamethrowers.
