After, shall we say, "mixed" reviews, they are probably having trouble unloading the "new Halo", at least the price is coming down.

Gamespot is a good review, I have read others that say there are ugly "poor graphic" levels mixed with beautiful "new gen" levels, I have not played it.

Frys always sells stuff for cheaper. Right now in their ad (for the local store, not sure about online), they had DOA4 for $49.95

i bought it on lauch day, so far im on like level 5, im just not enjoying it... i really wanted to, hell i paid for it! not sure what it is maybe the slowness or somethin, im just not diggin it
