a bunch of my friends have killing floor so i was going to buy it next time it went on sale for 75% off or more, and it's currently 85% off! i'm going to get the game, but should i also get the 6 dlc character packs for $1.79 more? if you have one or more of the killing floor character packs, are the additional characters significantly different from the ones in the base game? they regularly go for $1.99 a pack, but with the midweek madness they work out to 30 cents a pack. are they worth an average of 30 cents a pack, or should i just get the game and save the extra $1.79?

Exactly what it sounds like. More character skins. If you don't care about what you look like then don't worry about it.

They're just some character skins, nothing more or less significant than that. I ended up buying them all over time. I got more than my money's worth of entertainment out of Killing Floor, so I saw the packs as a way to further support Tripwire and get a little bonus to play with as I continued enjoying the game (which I would have done regardless of the existence of the character packs). Before you buy the packs, you should make sure you actually like the game itself.

thanks @Demoskinos and @Savage -- just what i wanted to know! since it's just skins and not different behavior i'll keep my $1.79

I haven't actually bought any of the character packs but damn, I will say some of the character packs are hilarious. I've been tempted to buy the chicken recently...
