Build Your Datacenter vs Reactor Defense

Turn a small server room into a growing data center business. Build Your Datacenter is an isometric management game about making the most of limited space, hardware and resources. Place racks, add CPU, GPU and storage capacity, and match your setup to the jobs your customers need. Every expansion brings a new decision. Keep equipment cool, balance electricity supply and demand, and choose from solar, wind and nuclear power as your operation grows. More hardware creates more opportunities, but it also means more costs to manage. RUN THE BUSINESS BEHIND THE MACHINES - Plan your layout and expand your server capacity. - Take on tenant contracts and balance workloads with available resources. - Hire staff to automate daily operations. - Maintain equipment and prepare for unexpected breakdowns. - Purchase land and develop your expanding facility. - Manage your budget and support the local community. Choose your next investment: more capacity, stronger infrastructure or a healthier budget. Your decisions shape the business.

Rogue machines are crawling toward your reactor core. You have turrets, scrap, and a build that gets stronger every run. Hold the line. Reactor Defense is a deep tower-defense game about the build you grow over time. Every run earns Mastery XP that permanently unlocks new evolutions, awakenings and upgrades, so no two runs and no two players end up with the same defense. TWELVE TURRETS, TWELVE EVOLUTIONS Gunner, Cannon, Mortar, Cryo, Arc, Lance, Warp, Flak, Corrosion, plus the Amplifier, Booster and Salvager support turrets. Every turret can evolve into a specialist: Sniper, Missile, Tempest Coil, Saturation Battery, Singularity and more. Evolved turrets climb to level 20 and unlock an Awakening, a signature power that switches on at max level. Several evolutions fire powerful ultimates on a cooldown. MASTERY: A BUILD THAT CARRIES FORWARD Spend XP on permanent upgrades: per-turret damage, range and fire rate, starting scrap and core strength, bigger Field Kit capacity, and the Overclock License, which lifts your turret level cap. Your progress is saved automatically, run after run. THE TECH TREE: CHOOSE YOUR RUN Each run has its own run-wide tech tree. Junctions force a choice, and taking one side locks out the other, so every run is a new set of trade-offs. PLAY YOUR WAY Choose your targeting priority on every turret: First, Last, Closest or Strongest. Aim a max-level Lance along a fixed line and burn everything that walks the lane. Place power-up nodes like Damage, Range, Rapid, Bounty or Shielded to decide which turret earns the upgrade. A fixed Daily Challenge gives every player the same map, modifiers and enemy seed each day. Opt into harder Modifiers such as Glass Core, Blitz, Fog of War, Austerity and Overcrowded to raise your score multiplier. Trophies record lasting achievements and grant small permanent bonuses. AN ENEMY THAT FIGHTS BACK Flyers, armored brutes and bosses come at you, and some enemies disable or destroy your turrets. Core Instability events, mega-boss choices and power-up nodes keep you deciding under pressure. Use Field Kits, one-shot tools, to turn a bad wave around.
