Apart from being extremely short (beat it in 4 minutes lol) it's a fully functional campaign, but way too short to be worth it unfortunately. Only one issue, bots fall off of the ladder on chapter 1 allot. Other than that it was fine. Chapter 1 was quite bland, the finale was pretty cool though. But that's about it. Navmesh worked perfectly. No glitches/bugs. Not bad, just needs to be alloooot longer for it to gain a higher rating :)
