Halo CE is a certified classic. The campaign does an excellent job of establishing the universe while providing amble variety in level design and gameplay variety. From linear corridors to large open areas, to sniping across valleys the first half of the campaign is everything you want from an FPS campaign. The mid game twist adds both to the story and gameplay in equal measure, However it is from here that Halo begins to run out of steam. The last few levels have you going through the same areas as eariler missions just with hordes of enemies, which is the only major blemish on this games legacy. Thankfully the game picks up again in the last sequence to end on a high.
The multiplayer of this game feels like the most fun alpha ever created. The gunplay feels as good as modern shooters but wonky weapon balancing and spawning into bullets stops me from saying its objectively great but I had lots of fun regardless.
Overall while showing its age in places CE is still Awesome.
