The 24-wave campaign now reads as six operations, with vanguard, main assault and final push phases in every battle. Campaign progress and tactical choices are clearer. Optional rewarded supplies are available once every two waves from wave 3; you can always continue without watching an ad.

Merge three tier-one troops of the same type again to create a tier-two unit. The selected troop keeps its evolution path and position. From wave 7, flying enemies cross the cliff and attack the rear. From wave 9, ranged spitters fire splash attacks from behind the entrance. Intercept air with rifles or artillery support and counter spitters with mortars.

Three acts and 24 waves, with new bosses at waves 20 and 24. Shield wardens and chargers change how you defend each lane. Repair your base between waves and choose repeatable late-game boosts. Fixed ordinary enemies appearing as black squares in TestFlight.
