Spider Mine Layer and choke points – need I say more. :) I really like this map. It is small and therefore good for very few players. The key to this map is to control the chokepoints. You can mine the small, narrow entrance behind your Power Core to prevent sneak attacks. It is imperative that you control the center node, and Spider Mines can be instrumental in doing this. Sprinkle liberally and wait for all heck to break loose.
It is not as imperative to have teamwork and this map, however working as a team can allow one team to dominate and win the map very quickly.
If you control the node behind the enemies Power Core (next to the narrow passageway), make sure you use Spider Mines to prevent “on foot” attacks. A persistent Manta pilot can make it through the passage, however Mantas are fairly easy to counter attack on this map because it is so narrow.
