Artificial Stupidity: The AI in this game was not exactly top of the line- civilians and your Company allies tend to get slaughtered. Fortunately for you, the enemies, though more numerous, are just as dumb.
Cool Car: Your character begins the game in his own garage, a personalized muscle car close at hand. It likely gets destroyed fairly quickly, but there are many more cool cars to use.
The Corruption: Orgone energy can go bad, resulting in the "Red 6" disease.
Critical Existence Failure: Characters on foot drop dead or even gib into pieces without any prior sign of damage, but vehicles avert this By having sectional armor- even if your front or side armor is shredded, you might be able to beat a hasty retreat with intact rear armor. If your armor goes and your chassis starts taking damage, your vehicle will emit smoke and flames as it nears destruction- your signal to get out and find a new one or risk going boom with it.
Cyborg: The Leper Gang use cybernetics to compensate for lost limbs.
Law Enforcement, Inc.: The Company are a gang of self-styled mercenaries and ex-military types who have protection contracts with various Outsider settlements. Stadium City hadn't been able to make payment as of late, hence their being open to a Red Sixer assault.
Made of Explodium: Orgone accumulators and transformers, as the energy itself appears to be quite volatile.
Liddy: Watch yourself 'round the accumulators. When they blow, they tend to make a mess.
Outrun the Fireball: Happens several times, beginning in the second level. You destroy an Orgone transformer belonging to the Leper gang, and have to escape the pit where it is located before it blows.
Sliding Scale of Villain Threat: Starting out with the Red Sixers, then the Leper Gang, then the Templars, then ancient Aliens entombed under Area 51, then wrapping all the way around back to the Red Sixers again for the finale.
Sniper Rifle: Your basic assault rifle can sprout a scope to become one. Its high power versus infantry is offset by its relatively rare ammo pickups.
Swiss Army Gun: This game makes use of Standard FPS Guns, however they are uniquely housed in a single, transforming rifle which changes out its barrels depending on the type of ammunition being used: bullets, shotgun shells, rockets, grenades, or a rotary saw blade. All you need to do is pick up the prerequisite ammo to use that gun's function, much like Accolade's prior Eradicator.
Tempting Fate: It's almost always a bad idea to get out of your car if there are enemy vehicles around, since it's very easy to get splattered by them.
Wake Up Call Boss: The first time you fight the Red Sixers boss at the conclusion of the opening level, you may find him unexpectedly tough. Use rockets to maximize your chances of success.
Weaponized Car: About half the game is played from behind the wheel of these, known in-game as "Battle Rigs." It's mostly cars with the occasional motorcycle (and, funnily enough, a Weaponized Forklift), but the cars range from the somewhat plain-looking Company minivan to the bizarre buggies used by the Lepers and Templars.
Wretched Hive: Stadium City has hints of this, but it gets ransacked by the Red Sixers before we can see much.
The Virus: "Red 6", which turns the skin of it's victims bright red, increases their size, strength and aggressiveness, makes them cannibalistic. It even makes some people, like the Red Sixers' leader, sprout Spikes of Villainy.
