CoreShield 2199: Tower Defense

Monsters and robots are advancing on your fortress. Build towers, call in soldiers, and hold the line. CoreShield 2199 combines real-time 3D tower defense with intuitive controls and a freely movable camera.

25 maps. Always a different challenge.

Defend verdant valleys, icy outposts, coral islands, lava fields, and futuristic cities. Each map features unique attack paths, a suitable fortress, and a distinct enemy faction. Adapt your strategy to the location.

Five labyrinths with unique weapons.

Fight in a castle, a spaceship, an underground bastion, an underwater station, and a smelter. Intricate corridors and passageways determine which objectives your defenses can reach. Soldiers utilize the interior pathways and retreat to the infirmary to heal.

Each labyrinth has its own arsenal: ballistae, catapults, and pitch barriers in the castle; prism lasers, ion launchers, and stasis projectors in the spaceship; Bolt guns, mortars, and winch barriers in the mine; harpoon launchers, pressure cannons, and sonar stations underwater; rivet guns, slag throwers, and steam barriers in the smelter. Unique weapon models, projectiles, fields of effect, and sounds make the equipment recognizable.

A defense that works together
Impulse turrets engage single targets, artillery holds back groups and armored enemies. Cryo fields slow down invaders. On suitable castle and nature maps, archers complement your deployment. Upgrade your turrets through three levels and see the effect of each upgrade before you spend your credits.

Soldiers by your side
Tap the fortress to call in reinforcements. Soldiers move automatically to enemies and defend their assigned area. Injured soldiers retreat to the castle to recover. On Hard difficulty, soldiers can fall in battle.

Your pace, your choice
Choose Easy, Medium, or Hard. Pause to plan, speed up the battle, or launch the next wave while you're still fighting the current one. Move, rotate, and zoom the camera to keep track of paths and building sites. Saved missions can be resumed later.

Clear rules. Room for strategy.

No potions, no consumables, and no in-app purchases. Your building sites, upgrades, and the strategic deployment of your soldiers are what matter. Earn up to three medals per map and difficulty level.

Missions can be played offline and do not require a game account. After completing a level, a full-screen ad may appear if you have an internet connection. Ad availability depends, among other things, on your privacy settings.

Hold the line. Protect your fortress.
