Grid Runner

The player has a pool of money, a base with cores to protect, and tower emplacements.

The goal is to strategically place towers to defend their base from incoming enemies.

Different kind of enemies require different kinds of towers to be able to destroy them.

The enemies consist of an alien species that is after your base.

These include small enemies and easy to kill enemies, slow and giant bosses, flying enemies, lightning quick enemies that require slowing down first, etc.

Towers consist of gun emplacements, flamethrower towers, anti-air towers, laser towers, and many more.

The enemies are after the power cores and pick these up after walking close to them.

Some enemies can carry several power cores at the same time and should be an priority.

When a power core is dropped, it slowly returns back to the power core, but can be picked up whilst returning by enemies.

The player loses when all cores are successfully stolen by enemies.

Unlike its predecessor, this game features coöperative and competitive multiplayer.
