- At the very start of the first game, you're supposed to watch a fellow miner get into an argument with a guard and then get killed, sparking a riot and subsequently the rebellion. However, if you go past the guard and miner grappling with each other you'll trigger the script where the guards start shooting at you prematurely. Normally, this would have been a bad thing since you can't fight back until you grab the baton from the soon-to-be-dead guard, but if you stand behind the grappling duo the guards will shoot the grappling guard, killing him - and the miner will keep wrestling with empty air before falling to the ground and dying for no particular reason.
- Throwing a remote mine on Exposition Fairy characters in the first Red Faction game. Their animations would still show them talking civilly with you, but all of the dialogue will be replaced with them screaming. After they're done, they'll go right into flailing their arms and acting frantic. Funny!
- In Red Faction II, there are several conversations you can hear between NPC's:
- In the second level of the first mission, you can hear Sammy and R.B. talking outside of a ventilation shaft. Sammy asks R.B. to loan him twenty grand. He declines, as Sammy begs. R.B. walks away while Sammy asks if he can give him a ride back home over the weekend.
- During the raid on the Public Information Building, there is a closet with a man and a woman. The man starts to ramble on how they were only having a meeting, and that the woman (named Stewie) was scared. The woman tells the man, Charlie, to shut up, and the player to go away and shut the door(which may be already shut).
- In the Catacombs, two G.I. Jones are setting up an automated turret. They get nervous about Alias after hearing Spencer's team get wasted (the soldiers at the start), then they talk about the Processed. One asks if they (the Processed) have sex, and the other replies if he's hard up for a date.
- Another conversation can be heard between two more G.I. Jones in the same level. When you're out of the burial area, one soldier states that the Processed in the area were the last ones they sent up. Another states that the last one looked like his cousin Todd, to which the first replies that Todd was already ugly to began with.
- In the first level of the Nano Base, two technicians are talking about the Processed. One states that they smell like roadkill, while the other says that they are the way of the future, and that they (the technicians) might as well be dead. The first then says that they at least bathe every now and then.
- How does Alias force Sopot to comply with him when they meet face-to-face halfway through Red Faction 2? By slapping him across the face in what should be a serious scene, that comes off as hilarious. Like how Alias swings a grenade launcher at them but only has a light slapping sound, or wears the guy's hat almost immediately afterwards.
- Red Faction developers seem to have a habit of including silly weapons. Behold the development cycle of the mighty Ostrich Hammer
- And Mr. Toots... need I say more?
- Sgt. Winters from Armageddon has this comedic gem in the lava level:
Sgt. Winters: You ever notice how when bad things happen - I mean the absolute WORST things imaginable. Horrible stuff - there's always a Mason around? Now I'm talking about shit you couldn't even dream of happening... y'know, it never fails!
- When Darious punches out the Jerk Ass Colonel, which doubles as a CMOA:
CO: Don't think this changes things. I'm still bringing you in.Mason: With all due respect, sir- *punches the CO* You're an idiot.Sgt. Winters: Damn, Mason, you just punched out my CO. Now what am I going to do with you?Mason: Well, you sure as hell can't detain me.Sgt. Winters: No, but I can thank you.
- Pretty much any conversation between Darius and S.A.M. whenever something bad happens and he asks her for a solution:
Darius: Got any ideas S.A.M.?S.A.M.: RunDarius: Run? That's not a plan!
- "When Darius first encounters a walker"
- To say Games for Windows Live was a hated element of the PC version of Red Faction Guerrilla would be an understatement. When Nordic bought the series from THQ, they eventually stripped it out of the game... and added a new Wrecking Crew map that consists of the letters 'GFWL' in an otherwise empty space, letting the players take out their hatred directly.
- In Guerrilla, you can kill your brother Dan during the first mission by hitting him with your hammer after he's don't talking. This leads to a Non Standard Game Over screen with an extra message: "WTF? You Killed Your Brother!"
