Extinction features many different choke points around the map, as well as a lot of cover for infantry to counter vehicles.
A Sniper spawns on the middle deck, and a Wrath also spawns in the middle, just under the center infantry pathway. Each base gets a SPNKr Rocket Launcher to counter enemy vehicles.
The map supports all standard gametypes, Strongholds being my favorite.

If anyone has any criticisms, please let me know, I want this map to be the best it can be.
