i played online with cruithne yesterday
it was really cool...there are no limitations on online play
you can voice chat, choose every map, have npc`s,make teams and whatever you can do in an ofline match
we where both on 1 team against 2 npc`s

cruithne had a hard time keeping the npc`s out of his base and i didnt really have the recources to help him...i mean i send a couple of units but it was not really much...
anyway after a while i filled the enemy beach with tons of giant tanks while i barraged them with battleships and my carrier(got to love that)
so i kept sending in units on the beach and i was about to beat one of the npc`s but then i had to go upstairs and the connection broke...
kinda sucky way to end but it was fun anyway
