Cyber Defense: Tactical Mainframe
Conquer progressive multi-road defense campaigns with dynamic layout transitions, branching Tier-3 upgrades, and zero-loss saves.
Cyber Defense is a tower defense game. Place turrets beside the road to stop each wave of attackers before they reach the mainframe, and spend what you earn between waves on new turrets and upgrades.
There are four turret types: Tesla pylons, plasma, cryo and railgun. Each upgrades twice, and the last upgrade branches into one of two specialisms, such as a stun or a burning area.
The campaign runs through four sectors of 20 waves, each on a new road layout, from a single winding path to twin choke points. Your campaign is saved as you play, so you can stop and pick up where you left off.
