Pros:

- Pretty fun, and a decent enough length
- Some humorous and witty graffiti
- Custom textures and the such
- Cool ideas, like the box and warp counters
- Fun Finale
- Funny Easter Eggs
- Crated items were pretty cool, as well as the TnT and Nitro
- ICE! It was funny watching the horde skate across it
- I liked the cutscene, it was simple, but cheesy

Cons:

- A bit much on the hordes, but seems to be more of an issue on Advanced and Expert
- Special Infected didn't seem to do too much overall, but it's the design of the levels, so it can't be helped too much, the hordes made up for that
- I can't think of much, it's fun enough!

Conclusion:

A pretty fun campaign to play, a bit tough with bots (friends were busy, so I couldn't play it with them). I enjoyed reading the graffiti, and some of the easter eggs that were present in the campaign. The one with the Boomer had me being careful with the other saferoom ones!

The finale was fun, and went on a decent amount. When I seen Tanks spawning during it, it made me nervous.

The cutscene was great. It reminded me of those cheesy looking cutscenes that some developers (like Naughty Dog themselves!) did on PSX games.

I'd recommend it if you're a fan of the Crash series, or just want to play something fun over all. 

Also the two small Spyro easter eggs were awesome :P
