Mostly crap, a few good ones.
Intro and menu - Definitely okay, aside from barely being able to read the names. I like the cartoon on the menu too.
Joeypwnsjoo - Terrible animation, sound, and plot, but watchable.
Cum - Amusing for the first few seconds, then it's just repetitive. Music is terrible.
Flee - Aside from "Hot damn I love playing doom", nothing salvageable.
Zacid - Shouldn't be on Newgrounds, It should be on Youtube,
Viperstudios - Very poor animation and voices, but quite amusing.
Stiff - I actually like this. It has a rewarding payoff, and the art style and Conker's Bad Fur Day music make it all the better.
Joeybang - Honestly, the animation is ok, but the music makes it nearly unwatchable.
Catoblepas - Definitely the best animation, and my favorite out of the lot. the music gets a bit annoying, though.
Squeef - It doesn't look good at the start, then It gets good with the art style and the music, but then you went and killed it with the I'M GAY and transition to a silent loop of the first scene from Flee's flash.
Newshape - Crap. Aside from the relation to the NG portal, absolutely crap.
Robinholmgrim/Kelch - Honestly, this was so bad that I couldn't even watch the whole thing.
In general, this collab is stupid. There are a few good flashes in there, but it's mostly garbage. 4/10, 2 vote.
