I apologize if this isn't in the right place, I'm fairly new here

But onto my question: I've had some fun playing WZ the past two or three weeks, but one of the things I'd really like to do is a just-for-fun playthrough using cheats. I could barely wait to use my laser satellite and Archangel missiles on those weak Scavengers! Here's the problem, though; for some reason, using the cheat "Research All" doesn't give me all of the bodies. I'm missing several of them: the black set of Retaliation, Redemption, and Vengeance, along with the Wyvern and Dragon bodies. I'm also missing some weaponry, such as the Stormbringer, Heavy Laser, Plasma Cannon, EMP Cannon, and the like; and I'm missing some of the turrets, like the Wide Spectrum radar and the Heavy Repair turret. Finally, I don't have the Uplink Center/Laser Satellite CP, or any of the fortresses.
Essentially: I'm missing a lot of stuff in single player. I tried using the cheat "Give All" to rectify this, and while it did give me the Vengeance, Retaliation, and Redemption bodies, I didn't get any of the other turrets or structures. I was told that this could be fixed if I added all of the Skirmish/Multiplayer content as a mod to supplement the single-player Campaign mod, but frankly, I'm at a loss for where to start or how to do anything. I'd appreciate it if somebody could do that (as long as it isn't too much trouble) or if somebody could at least tell me how to do it myself. Thank you
