I have been playing the demo of Bad Company 2 since it came out on January 28th.  I have found a few tips for you when playing the Port Valdez map.

If you are a Attacker…

• When parachuting in on the first spawn point if you hold your stick to the right you can land on the mountain that overlooks the first 2 M-Com stations.
• The defenders cannot come all the way into the first spawn area, but can get very close.
• Keep your UAV just out of harms way.

If you are a Defender…

• You cannot go all the way into the first spawnning area.
• Most of the time the TOW weapon needs @2 hits to tanks.
• Snipers can last considerable time if they hide under/near trees, bushes, and rocks.
• Attacking snipers will come out to the edge of the cliff.  Position a sniper in a parallel vantage point.
• If at all possible get at least 1 person behind the Attackers.  That person can eliminate various enemies that are going for the UAV, and more.

This board is well designed, and can offer many good battles.  There are many hidden spots for snipers, and other personell to hide at.  Familiarize yourself with this board, and search out areas that you find work well for you.  Being that you are in the snow the clothing of the players blends well.  It is cold out there… Watch your eczema, Bundle up, Kill anything that moves.
