I'd love to see the use of Half-life 1 NPC's, but it's understandable what problems that brings to the table (Required Addon/Original Game)

Other than that, it'd be cool to see a ranged healer, maybe a red coloured scanner that uses the TF2 healing beam as effect?

Mortar Synth perhaps?

Or maybe a Riot Shield Metro Police?

You know what Petski, you just gave me a really good idea for a healer. I'll see what I can do

cars?

Habibi

Mini-gunship.
-aerial, high DPS, bigger than Valkyrie, making it a bigger target, but higher damage per hit.

Carpet Bomber
-Combine Heli dropping bombs.

Hunter squads could be a thing, a flechette only hunter team

maybe a mob that takes control of enemy mobs?

Aero175 Thats actually a really good Idea I'll have to look into that

maybe a strider but instead of the normal gun it usually has it just has stalker lasers, downscaled and with a limited time as a legendary unit?

another suggestion is maybe (if its even possible) make a way to add addon npc's

maybe you can add a combine sniper? i don't know if you need to add a new model for the sniper but i think it should be possible

Here's my idea:

What about engineer? He will build (spawn) combine turrets which will attack enemy npcs.

How about a zombine that can't die from his grenades.

How about a zombie cave, thats just some merged props, that spawns like a set number of zombies per round? Maybe a rebel or combine cave could be built.
