In a struggle to reclaim a besieged realm, players defend a line of towers against hordes of invading forces. Strategically positioned on a battlefield, these defenses are the last line of defense against an army of relentless enemies.
The core mechanic involves positioning these defenses to best utilize their unique abilities and strengths. Players must carefully consider the strengths and weaknesses of each tower against the various types of incoming enemies. Effective placement and upgrading can mean the difference between victory and defeat.
The ultimate objective is to protect the realm from the invading forces, but the challenge is made increasingly difficult by the introduction of new and more formidable enemy types as the game progresses. Players can test their skills and strategies without download or registration, and the game runs directly in the browser.
