Sanctum

Overview

Sanctum is a tower defense game played from the first-person perspective developed by Coffee Stain Studios, built on Unreal Engine 3. You play as Skye, an elite soldier protecting her home town of Elysion One from a devastating alien horde.

Gameplay

The game is split between a building phase and an extermination phase.

Building Phase

Players build and upgrade eight different towers, as well as having the ability to upgrade Skye's three weapons.

Upgrading

During the building phase, players have to option to upgrade their towers and their weapons. Both towers and weapons have five levels of upgrades, each costing more than the last.

Extermination Phase

Waves of varying creatures will then attempt to reach the core in the extermination phase, and the player's mission is to prevent them from doing so. The player controls Skye to provide support to the towers built during the building phase. Waves are formed of either a single enemy type or a combination of two.

DLC

Sanctum's debut DLC was released on 26th September, 2011. Content included two new maps and three extra towers. In addition to the DLC, a free update entitled Elysion One Overrun! brings two more towers, a new map, and an extra weapon for Skye. A Second DLC Map pack was released on October 12, 2012.

Towers

Anti-Air launches missiles at the enemy and causes blast damage to any target within the area.
