• Every sector is rebalanced, and three towers can no longer carry one. Mk III upgrades cost more, talents are toned down, later waves hit harder, and clearing a wave pays more, so spread your defense across many towers. • During a boss fight, bosses now jam your most valuable towers for a few seconds at a time. • If a sector's final boss reaches the core, the run is over. A warning appears when it arrives. • Hard mode: regular enemies are faster and bosses are tougher, tuned sector by sector so every Hard sector stays winnable. • Overflow: endless bosses are lighter, so the climb goes further. • Talent, Threat Database and help text match the new numbers.

• Tower talents: at Mk III, every tower picks one of three talents. There are 27 in all, from Storm Rounds and Napalm to Blizzard and Bounty Drone, and the tower's crown takes the talent's color. • Hard mode: clear Sector 05 to unlock it. Regular enemies are tougher and faster, the core has 15 blocks, and scores count 1.5× on the same leaderboards, with separate Hard stars. • Sandbox: practice on any map with infinite credits and a spawn panel for every enemy and boss. Tower panels show damage per second, so you can compare talents. • Redesigned bosses: all ten are now creatures, including a crowned armored virus, a three-headed serpent, a horse-headed siege walker, a kraken and a colossal eye. Each one gets an intro card when it arrives. • Bosses now enter at the portal and walk the whole lane. • The boss countdown always runs at normal speed. • Lane arrows point toward the core. • Sound comes back on its own after a call or notification. • Regular enemies are 12% tougher.
