Our: Defense 2021

Our: Defense 2021 is a tower defense game in which you place and upgrade towers to repel alien swarms. You fight across locations on Earth, adapting your tactics to the conditions and choosing where and when to build.

Towers and upgrades

You start with two towers and unlock more as you open new locations. Each tower can be improved using credits earned by killing enemies; upgrades increase its strength, attack speed and range. You need to decide which towers to build and when to upgrade them, since some are nearly useless in certain locations while others are essential.

Weapons and locations

The towers attack with weapons including gigantic machine guns, shotguns, gauss rifles and a giant laser created using alien technology. The game has 18 locations, each calling for its own tactics and strategy. Missions last from several minutes to several tens of minutes.
