After finishing KTA4 and Phoenix I had to stuff my face with some more Ryoko maps and this came in clutch. This scenario uses no AR and has pretty unorthodox progression. Not as convoluted as the other reviews say, methinks. Also has a lot of funny references to Rubicon so maybe you might want to play this after you've played that first
Highlights Marathon Infinity's weapon balance and enemy design. No reason not to play this if you're at all a fan of Marathon combat.
If I have a particular complaint, it is that the health/oxygen bars have a strange clipping at their edges (even and most notably when they are full). Although, I wonder if this is at all fixable...
EDIT: setting the size to Normal slightly mitigates the issue, but is no fix.
Beautiful sprites and mapping. Nice combat on TC. Weapons that feel straight out of Unreal Tournament in the best possible way. Can feel quite different from regular Marathon at times, but perhaps that is more to its credit than anything else.
Arcadey feel combined with the long breaths typical of Marathon campaigns, combat polished to an absolute fault and with its own identity, plain old good mapping and a satisfying arsenal. Everything garnished with a fairly good story that explains various new gameplay elements in an immersive way and provides awesome setpieces to play through, as well as great balance even and especially on Total Carnage. I see very little reason not to treat yourself to this scenario if you are able to.
