I wish only pain and suffering upon the developers.

10 gigs? guess what you're getting in those 10 gigs. PURE SHOVELWARE.
EVERYTHING IS AWFUL

Pros:
zombie mode was fun.

Cons:
LITERALLY EVERYTHING ELSE.

CONCLUSION: DO NOT BUY.

This feels like a tech demo that should have not been released.
Yes, it's really that bad. (I was surprised it even started up tbh)
-Grass has the same traction as tarmac.
-The AI gets stuck on the walls in demolition derby.
-The AI will bum rush you in demolition derby.
-Boost has a dumb FOV effect.
-The character names feel like temporary ones for when a game is in development. (Xmas-2011, I'm not joking)
-It whinges about not finding the Windows Hardware Experience Index on every startup.
-The grammer just feels off.
-The game needing 10GBs of disk space for this "experience"
-The physics are just silly.
-The AI is far more A than I.
-The AI can take corners as if they're on rails.
-The Splatout gamemode is a lazy ripoff of Carmageddon.
The conclusion: Don't buy it for a serious experience. Only buy it for the memes, achievements and posting witty reviews on Steam.

Absolutely terrible. Blatant cash grab. The fact that this is still being sold is an insult to fans of the series.
