Yes Seko is correct, the Zombie Crawler is not included in the pack. The 18+ Model Pack 22 includes the regular
Brute, which can hold any firing weapon (the very same character which can be bought separately), it includes the
Axe Brute, which is similar, however has a few texture variations (more blood and a different suit color) and wields its own default axe weapon, there's the
Chainsaw Brute which speaks for itself hehe, two variations (texture and script) of the
Dogman, two variations (texture and script) of the
Lobotomy character, and three variations (texture) of the
Dante Beast. Only the regular
Brute out of all of those is available separate in the GC Store.
For multiplayer maps, I'd check out this thread -

Just have to go through and find the MP ones, and yes some of the links I've found were dead, others however aren't. Hope you find what you're looking for man!
