Left 2 Die

Left 2 Die is a Blizzard-made cooperative custom map in StarCraft II.

It was published in April 2011.

Overview
Based on Outbreak, players can choose a difficulty level. They control a terran base. They defend against "zombie" attacks while collecting biomass, obtained by killing special zerg units and destroying infested buildings. This can be spent at a science facility to research new units and structures. These upgrades apply to both players.

Enemies will include special large infected with special abilities.

Like in Outbreak, a day-night cycle exists. During the day, players have the opportunity to take out infested terran structures and reinforce their defenses. Victory is achieved when all of these structures have been destroyed.

Night 2 Die
This is a survival mode version of the map. Here, night never ends, each enemy wave is increasingly more powerful and infested terran structures are invulnerable. The objective is to hold out for the longest possible time.
