Singularity is a minimalist tower defense built around a single core you have to keep alive. Enemies close in from every direction. Your core fires on its own - your job is to decide what it becomes. Every level-up offers a new upgrade, so no two runs play out the same way. FIGHT Waves escalate relentlessly, and every tenth wave sends a boss. Keep the core alive, stack up kills, and push your score as far as it will go. BUILD YOUR RUN Thirteen abilities to level up mid-run - damage, fire rate, range, burn, chill, poison and more. Reaching max level on all thirteen in a single run is a serious challenge. PRESTIGE Cap your four base stats and prestige to turn a single run into permanent power. Spend prestige coins on Head Start, Second Wind, Twin Level-Ups and Scrap Doubler - then chase full completion by owning every upgrade and wiping the slate clean. FEATURES - Simple one-thumb controls - Fast runs that escalate quickly - Thirteen upgradeable abilities - Boss waves every ten waves - Prestige progression with permanent upgrades - Game Center achievements - Remove Ads available as a one-time purchase
