Adapt and survive.
OVC is a tower defense where enemies move along a grid to seek and destroy your bases. Upgrades, weapons, and strategy are your only hope at delaying the inevitable.
Ten augmentations
Augmentations take bases to new heights. Soak damage, snipe enemies, freeze the board, spawn gravity wells, link bases in a network: each augment goes beyond basic stat upgrades to empower your base.
Enemies that evolve and support each other
Twelve enemy types, made more dangerous by the ones standing next to them. Guardians shield neighbors. Supports heal and buff the wave around them. Accelerators push everything else forward faster. Disablers shut your bases down, Detonators go out with a bang, and Spawners make the entire problem bigger.
Control the field
Bases aren't your only tools: that's where the weapons come in. Deploy autonomous Bots, place Mines along approach lanes, install Turrets for ranged cover, and lay down Gates to afflict enemies passing through.
Research
Keep labs going around the clock to unlock more powerful tech.
Upgrade, upgrade, upgrade
Upgrade base stats, weapon effectiveness, augmentation powers, research levels and more.
A reason to come back each day
