In the Team Deathmatch variant, controlling the structures around the Gas Station is a good strategy for dominating a round. The Gas Station is at the very center of this map, along with several other small structures to its south and east.
While the buildings may seem like safe positions from which to defend, keep in mind that almost every wall is destructible. The crossroads at the center of the map is a good place to avoid.
Both the paved and dirt roads offer long sightlines and are frequently watched by recon and support players looking for easy kills. If you want to avoid getting sniped, head for the woods north of the Gas Station.
Here, you can find decent concealment that is ideal for launching ambushes. However, as in any Team Deathmatch, never wander off on your own.
Stay with at least one other teammate, or form a small posse of teammates and orbit around the perimeter of the map looking for easy prey. Being constantly moving is preferable to defending one static position unless you have the dedicated manpower to make a stand.
