I figured that this would be much more interesting to read than my paranoid rambling.
I thought up a Half-Life 2 singleplayer mod in which the player is on a team of npcs that have a certain "class". Think of it as a sort of TF2 clone with npcs, and yellow and green teams. The objectives for each level will be different.
Alright, here are the npc ideas, and being the cut content fanboy that I am, I'll be using some coding from Insolence once the mod is done.
conscripts - The lowest and most expendable, have a measly 30 HP
-Use city citizen male_02 models with jumpsuits that correspond to their team color
-carry ar1s alyxguns and shotguns.
medics - The closest thing to a humanitarian warrior you'll get on this quad-conflict battlefield. These guys are legally certified paramedics who have decided to kill the other three teams' forces while healing their own. They are higher in status than the conscripts and are more respected than them. Have 40 HP.
-Use HL2 leak medic skin, white shirt color changes based on team color. To prevent the cross from blending into red medics' shirt colors, it will have a white circle surrounding it.
-Typically use smg2.
grunts - The footsoldiers who decided not to turn around and run screaming when they were conscripts. Have 60 HP.
-Somewhat Ironically use the leak conscript model, clothing corresponds to team color.
-Better equipped than conscripts, carry OICWs and SMG1s
grunt majors - The grunts who were rewarded for their effort. Have 65 HP.
-have same appearance as the rocketeers.
-Armed with OICWs and Shotguns, usually accompanied by a grunt and a medic.
rocketeers - These guys are not popular with their teams on account of them being rumored to have an unhealthy fetish for explosions. Some say that they were secretly trained by Micheal Bay. Have 60 HP.
-Use a leak conscript model variant that has a helmet, trenchcoat, and radio backpack.
-Armed with RPG, keeps distance but not as far as the marksmen.
-Guarded by squads of medics to make sure he can get a few rounds in.
officers - These guys are officers, they passed the officer exams to become officers, and what did they get? Uncomfortable gas masks and silly darth vader-sounding voice changers They rally not-so-brave conscripts and send them off proudly to their deaths. Have 50 HP
-Use Metrocop model, and I bet you can't guess what their clothes do involving their team color.
-Carry pistols smg1s and smg2s
-Accompanied by squads of conscripts
marksmen - The socially awkward always aim better. I'm thinking 10 HP to compensate for their accuracy.
-Use the gasmask citizen model, corresponding clothes to team color
-Use annabelles and leak sniper rifles
-Have "long vision/shoot" spawn flag in hammer
-Prefer elevated areas rather than the front lines, obviously.
elites - These sons of bitches just decided to go above and beyond in the field. They were rewarded with what they describe as "cool voice changers" and "comfortable gas masks". Have 70 HP.
-Use the combine soldier model, corresponding colors and shit, dawg.
-Equipped with smg1, shotgun, oicw, and pulse rifle
Punk-Asses - Organic robots that are programmed to be asthmatic and support ground forces. Originally known as the Mobile Assault Crematorium MK1, they were renamed Punk-Asses when a red marksman who was scouting a blue area radioed in "Mission control, there are some punk-ass robots guarding the perimeter!" They are incredibly slow and not too bright, but when they are attacking they are a force to be reckoned with. They have 300 HP,
-Use the cremator model, immolator lasers and robes vary based on team color.
