Great world, horrible length, multiplayers ok for a few days, Single player is a Magikarp at level 1
7 chapters, and they pad the game by making the enemies dumber than bricks but accurate than your average character. The story itself is pretty self-explanatory. You're a resistance fighter who has to give supplies to the US Marines who are planning an assault on the western seaboard of the U.S.
The Korean back story is odd, but seems like it could be believable in a movie (wink wink Red Dawn-remake changed the main oppressor to the North Koreans instead of the Chinese). There are a few loose ends that never get tied up, like for example: the entire main storyline of the game. Also how the USS John C. Stennis got to Lake Tahoe(that is the single most baffling thing ever). The setting is nice, lots of post-oil suburbs, pre-rendered skybox labor camps, and a few cutesy little licensed restaurant chains. Also the 30 minute long tour of the "Modern community" post-oil suburban hideout.
The game has it's moments, Mortar strikes that go wrong, the opening statement that makes sure you root for the Americans and not the Koreans who are, well, evil. However, the moments start to dissipate pretty rapidly.
The Multiplayer, at first sight, is good enough. The Phased-line King-of-the-hill hybrid is a pretty fun play, but the map mechanics make some of the maps sniper havens or vehicle impound lots with a tank on one side and 6 Humvee without gunners on the other. The Kill-streak system is actually pretty innovative, It takes the CoD concept approach but instead of earning points just for doing things, those points actually count toward you getting anything from a Recon Drone, a UAV Hellfire run, or even the humble flak jacket. It's hard as hell, even on PC with mouse controls, because the guns are notoriously inaccurate unless you've got the right perks.
There's the usual amount of customization, but instead of sights and colors, you get types of red-dots, Acogs, and whatever else you can power through to unlock. There are plenty of perks to be found, most insanely useless, but serve their purpose in certain situations. The weapons are pretty cool and the games can get quite fun when you're just playing the Recon drone guy, but with all the fun comes caveats in the amount of quality servers and the legitimacy of most opposing players.
It's ambitious, but it fell quite flat. The single player would take my little brother 3-4 hours tops to beat on the harder difficulties. The game itself lends more toward the credence that this a world to behold for a short period of time, rather than a world to get lost in like other Resistance-type games(i.e. MoH: Underground)
Kaos Studios have done one other game of note, and that was another future-epic game called Frontlines: Fuel of War. Which dealt with a severely altered premise, but was just as short and just as hard in it's Battlefield-type setting.
Homefront was a logical step from Frontline, and a step made well, but going from a mediocre game to a game that was universally hyped to be the single greatest FPS ever, is not the way to go. However, we'll be seeing more of Homefront thanks to the overwhelming amount of Press, Pre-orders, and Purchases it got.
THQ has a new FPS IP, but where it goes I have no idea.
