Ok it may sound silly at first but I think it would make a great mod, using all the art from Half-Life 2-
The Combine:
They have the most powerful weapons but Resistance guirella attacks pose a threat.
Buildings-
Tower
Barricade
Vehicle factory
Drop off point (Dropships drop down units)
Units-
Soldiers
Striders
Gunships
Prowlers ect...
The Resistance
They are weaker than The Combine but have the ability to make any empty building into something to suit their needs
Buildings-
Recruiting building
Amoury (Turn normal recruits into pecific units)
Garage
Units-
Snipers
Attack units (with assult rifle)
Buggy
Xen Aliens
With no powerful human weapons they are the weakest but have the ability to teleport in from the borderworld (though this leaves a portal for others to come into Xen)
Buildings(if you can call them that)-
Gonarch (for headcrabs)
Healing pool
Nithalinth-thingie (Creating other units)
Units-
All the aliens from HL1
