One of the few well-made parodies out there of Left 4 Dead. If you play it enough, you'll understand some of the inside jokes that was portrayed in this flash.
1.) Louis eating KFC = There is always some idiot standing behind doing nothing. Eating a snack bucket of KFC is just one of the possibilities.
2.) Francis' departure = When you first play the game in No Mercy, at least for me, you realize you're being raped by these zombies since you really have no clue on how to exactly to respond.
3.) Car incident = ALWAYS an idiot shooting the car, always. Doesn't matter what you say, it's still shot.
4.) Tank appearance = Damn AI Director spawns a tank right infront of the safehouse doors. Resistance is Futile.
5.) Anal-shots from Louis = Something that is really irrelavent to L4D. An add-on of the flash i'd say.
6.) "What are the odds?" = You get these rare moments where an idiot gets smokered while the other idiot stares at the witch God knows what they're thinking, and finally you got zoey who just so happens to get pounced, which leaves one guy left, whom depending on the situation A.) Suicides | B.) Rage Quits | C.) Attempt heroism.
7.) Louis huntered = For some reason, people like to be blind and deaf, and not realize that there's that one person missing. "Hmm wonder where he is?" HE'S GETTING POUNCED MORON.
8.) Francis' Monologue = Inside Joke of the author, hell if I know why he put the face of some kid.
9.) Smoker incident = First time you get smokered, you'll know what it means.
The list goes on and on and forever more.
So yeah, great flash, woohoo.
