IMO Homefront is a pile of crap compared to just about any release of Call of Duty starting with CoD4!
game-play is choppy and glitchy to say the least..
the one thing for it though, is the campaign story
it breathes just fine.. there's a massive fan behind the enclosure
no point sending it in.. i've already repaired it a few times
first was the DVD Drive "open tray", fixed by adjusting the resistors on the laser driver board, then i replaced the DVD drive completely (swapped motherboards)
then i replaced the drive belt, cleaned and replaced the fans inside.
i think it's time for a newer one.. this one worked its butt off for 3 years
