I've played every Halo since the first and I have to say this is the least enjoyable, worse even than Halo 2. Solo campaign is short, many of the levels involve the same tedious gameplay on almost identical looking corridors/platforms - and lifts, so many lifts!! It's nice to look at but missing the soul of previous Halo games. The story/plotline is meaningless and impenetrable to anyone over the age of 14! I would struggle to recommend this.
