Zombie Survival Xtreme

Overview

Zombie Survival Xtreme 2.7 is a tower defense style survival map for up to 12 players split into two teams, played on a 192x223 map. Players have 30 minutes to hold off hordes of mindless zombies and special infected by building up their base quickly. The loading text describes four areas to pick from, labeled Easy, Medium (Co-op), Hard, and Extreme, and notes that zombies walk two blocks at a time, so maze building is the main strategy. Attacking a partner's tower destroys the tower you used to do it. The map adds a faster build speed and a Lightning Tower, and the chat commands -clearkeys and -noob are included. No heroes are listed.
