Lackluster single player, but great online options.
-The mechs move slow (realistically slow though)
-Prepare to spend plenty of time in the garage
-You'll want Xbox Live Gold
-When online, don't expect to be a hero
-THIS IS NOT HALO OR MECHASSUALT
If you can handle the above, then you'll probably enjoy this game-after you breeze through the brief, mediocre single player to get some decent parts. Then you can assemble a mech and hop online. Or you can buy a premade mech if all the assembly seems to boring and confusing.
The options online are huge. Free Battle (ranked or unranked) allows for simple deathmatchs/team DM's. Then there is the Neromius War. In order to participate in it fully, you'll want to join a squad (clan) so you can fight for territory of one of three countries- Morskoj, Tarakia, or Sal Kar -or participate in individual missions for money, which you can use to buy parts or premade mechs.
It wil take time and commitment to get the full value of Chrome Hounds' online play, but that value is one of the best for an online multiplayer game on the 360 thus far.
