Mombasa streets: fun when you're being tactical and looking around for audio files.
Tayari Plaza: Fun, but not necessarily remarkable. Except for the sky, that was amazing.
Uplift Reserve: Some pretty damn intense vehicle battles.
Kizingo Boulevard: Who doesn't like rolling around in a tank blowing -blam!- up?
ONI Alpha Site: The whole level was essentially a shooting gallery. Not that that's a bad thing, of course, but it got old.
NMPD HQ: Fun sniper skirmishes, and an absolutely epic final battle.
Kikowani Station: It needed more action. Less stationary targets, more enemy banshees flying around.
Data Hive: Good build on story, especially with all 30 audio files.
Coastal highway: Amazing mission. Epic vehicular gameplay, an epic final holdout, and it truly showed the full might of the covenant completely invading the city.
