Threshold Defense

Through inter-dimensional portals called Thresholds, hordes of freakish zombies and Dominion soldiers have been teleporting to Earth and threatening our very existence.

It’s time to put a stop to this using any means possible.

New Mode!

Threshold Defense is an all-new co-op mode based on familiar tower defense gameplay and pits you up against waves of marching enemies.

Make use of environmental weapons such as turrets, teleportals, and even mech suits to kill them all!
