CLUSTER - Roguelike Tower DefenseDefend your tower with strategy, not spam. In CLUSTER, you build your own upgrade system between waves using rotatable cluster cards. Colors, connectors, and positioning determine how powerful your tower becomes.CLUSTER is a tactical roguelike tower defense game built around a single central tower facing increasingly dangerous enemy waves. But the real battlefield is your cluster board: a grid where you place, rotate, connect, trade, and sacrifice clusters to unlock and improve powerful effects.Every connection strengthens your build. Every defeat earns meta points. And every new run gives you another chance to outbuild the next wave.<ul class="bb_ul"><li>One Tower, Endless Builds No maze building, no tower spam. Your entire run revolves around a single tower in the center, powered by the cluster board you create around it.</li><li>Puzzle-Driven Board Building Clusters contain colored cells with edge connectors. Effects only grow when colors and ports match correctly. Rotating, placing, and chaining pieces together is the core of the game.</li><li>8 Colors, 8 Effects Upgrade damage, attack speed, crit chance, lightning, burn, slow, stun, aura, and chain reactions into wildly different tower builds.</li><li>Roguelike Decisions Between Waves Choose from new cluster offers, manage limited storage, use trade charges, and decide which pieces of your build are worth keeping. Small choices snowball into major late-game differences.</li><li>Meta Progression That Carries Across Runs Spend earned meta points in the meta shop on permanent upgrades that make future runs stronger and open up new build paths.</li><li>Escalating Enemy Variety Fast enemies, durable enemies, and heavy units force you to adapt constantly. Later waves introduce elite enemies, shielded enemies, interceptors, and the mothership, which can deploy additional units into battle.</li><li>Four Difficulty Modes Easy, Medium, and Hard each feature 30 waves, followed by a Hardcore Endless mode with a Steam online leaderboard for players who want to push their builds as far as possible.</li><li>Sci-Fi Circuit Board Aesthetic A distinct visual style of neon circuitry, energy links, and futuristic interfaces keeps the battlefield readable while making every build decision feel impactful.</li></ul>
