I dunno what to say...
We were just searching for a random custom campaign and stumbled over this one. Crash Bandicoot and L4D2 in one package? To awesome to be true? No, it is even more awesome than you expect.
Every level is unique and has various moments that make you smile and cry at the same time. Smile because of your awesome childhood memories and cry because sometimes those levels can be very difficult.
The final stage is truly a FINAL stage. Me and my friends played it several times, nearly to perfection till we beat it, and still it was just a close win.
So if you searching a good custom campaign for a round with your friends...this is the one you should get.

Awesome Soundtrack
Awesome Leveldesign
Awesome Cutscenes
Awesome Everything

Sometimes there are some minor bugs. One time we had the problem that dead players didnt spawn in the main area, instead the landed at the end of the next level. But that was only the case when one of us hosted, so it might was a problem with his computer.

But still 10 out of 10.
