As a short distraction to play through once in co-op, it's decently fun. Can't imagine it being as fun in solo play. Otherwise this is mainly noteworthy as a historical curiosity for using Halo's engine. The disc doesn't have the final updated version on here so I can only even boot it if I disconnect my Xbox from the internet, it refuses to boot because it looks for an update that doesn't exist, so it's gonna be one of those rare games that I remove from my collection. Ah well, could've been a decent Halloween season replay.
