I enjoyed the closed beta more than I had thought I might - but driving vehicles felt very clunky (as other people I played with agreed). And though it was quite humorous at times it was more often frustrating.

Helicopters too didn't feel particularly good either when raising and lowering altitude - landings were often a very inelegant experience resulting in the aircraft pounding into the ground no matter how careful one was.

Played on Ghost level and the AI seemed somewhat unreasonable - knowing exactly where I was beyond all reason at times.

These issues aside was an enjoyable experience.
