    You simply need to host a System Link game, set the map to "Gravel Pit" the time to "15 Minutes", Round Win Limit to "1". Remember to select the defending team and start it up.

    You can do nothing, explore, take a nap or even hunt moose, either way when the game ends you will have a new achievement.

    Note: You do not need a second player/console.

    This is the hardest map based achievement. It requires a lot of communication and team work as well as a good understanding of the map. You’ll need to split up your defense between A and B. It’s good to have some power classes but don’t dismiss the scout just because of his low health! Scouts can dominate the defense on this map. You’ll need their quick speed to run between points, helping out where needed and stalling enemies. I good thing to remember is that if you lose the outside of B, you lose B. Putting sentries inside B isn’t always a good idea. Keep sentries outside to guard against rocket-jumping soldiers because once they are on the roof, they can take out most people who are inside with ease.
