Then the Blight woke up.

Kepra is a real-time strategy game built for touch: raise a base, mine the planet, research upgrades and command your army against an alien swarm that grows stronger every wave. No energy timers, no ads, no loot boxes. Just strategy.

TWO FACTIONS, TWO WAYS TO PLAY
• The Bastion Compact dig in. Constructor Drones build Supply Depots, Foundries, Pulse Turrets and hard-light Barrier walls around an armored Command Core. Siege Walkers out-range anything the Blight sends.
• The Vashari Drift never stay put. Their whole base is a flying Ark that lifts off and follows the ore. Structures warp in on their own, Drift Raiders hit fast and Void Lancers strike from long range.

A CAMPAIGN WORTH FINISHING
• Ten story operations across Kepra-10: storm the Sentinel Vaults, survive the Long Night, bring down a Hive Titan and carry the fight to the hive itself.
• Choose your people in most operations and replay every one for three stars.
• Three difficulty levels, from Recruit to Commander.

COMMAND THE BATTLEFIELD
• Call down Commander powers when the line is about to break: Orbital Strike, Overcharge, Rift and Surge.
• Research new weapons and armor, then promote veteran units as they survive the fight.
• Build walls to funnel the swarm into your turrets, or lift your Ark and leave the Blight behind.
• Fog of war, scouting and ancient Sentinels guarding rich ground.

PLAY WITH FRIENDS
• Online co-op for 2 to 4 commanders. Share a room code or use Quick Play.
• Local network (LAN) co-op on the same Wi-Fi.
• Friends join for free; only the host needs the full game.

SKIRMISH AND ENDLESS
• Pick your faction, difficulty and 5, 10 or 15 waves, then fight for the planet.
• Endless mode: see how long your defense lasts.

MADE FOR PHONES AND TABLETS
• Touch controls built for RTS: tap to command, long-press to box-select, double-tap to grab a whole squad, pinch to zoom and twist to rotate.
• Detailed 3D world with dynamic lighting, scaled to run smoothly on a wide range of devices.
• Play offline anytime. Internet is only needed for online co-op.

TRY IT FREE, BUY IT ONCE
The first two operations and Bastion skirmish are free. One in-app purchase unlocks the full game for good: Operations 3 to 10, the Vashari Drift in skirmish and co-op hosting. No subscriptions. No ads. Ever.

Kepra-10 holds, for now.
