Protect humanity’s last colonies from extermination in this tower defense and real time strategy hybrid. Fight the Xenos and Riven alone or with a friend, using a wide arsenal of towers, traps, mobile units, and strikes.

## About This Game
Colony Siege is a Tower Defense and RTS hybrid.
## Defend Your Colony

Whether fighting the Xenos or the Riven, no colony building is safe from
attack. While protecting the colony Citadel is your primary objective, the
enemy will not discriminate when it comes to attacking your colony.
## Use Towers, Traps, Strikes, Mobile Units, and Special Abilities

Defend with powerful towers that automatically form walls when placed near
each other. Use unique traps to slow, impale, burn, or bombard the enemy.
Build and command mobile ground units. Strike the enemy with satellite-powered
attacks, long-range missiles, commander abilities, and fighter sorties.
## Design Mazes Before and During Battle

Defensive towers and barriers automatically generate a laser fence when
constructed close together, allowing your mobile units passage while
restricting enemy movement.
## Embark on an Epic Campaign

Experience dozens of intense missions from a starmap with branching paths.
Press your advantage or repeat previous missions for extra cash.
## Fight Alone or with a Friend

The entire campaign is cooperative from the very first mission to the last.
Consolidate forces with a friend or combine different tactics.
## Battle Both Xeno and Riven Enemies

Defend against the relentless biomechanical xeno swarm as well as the
corrupted Riven that were once human. Both enemy factions behave differently
and require different tactics.
## Persistant Progression System

Earn money from completing mission primary and bonus objectives, and spend it
on persistent upgrades, new weapons, and different towers, traps, units, and
strikes. Unlock powerful perks to buffer your weaknesses or bolster your
advantages.
## Battle in a Wide Variety of Environments

Expect a constant change of scenery as you travel to different planets, moons,
space stations, and enormous mobile space platforms.
