Regal Tower Defense: TD Game

Regal Tower Defense is a tower defence campaign built around placement rather than volume. Arrow, Cannon, Frost, Flame, Lightning, Siege and Chaos towers each answer a different problem — armour, speed, resistance, crowding — and the levels are designed so that a wave you cannot beat usually means the wrong tower in the right place, or the right tower in the wrong one.

Aura Towers are the layer on top. Instead of attacking, they raise the damage, attack speed, range or elemental power of everything nearby, which turns a chokepoint into a kill zone and makes the shape of your layout matter as much as its contents. You can also buy Build Pads and place them yourself on valid terrain away from paths, towers, auras and the castle, so the map is partly something you design.

The campaign runs 50 levels across 10 worlds — Royal Meadow, Stone Pass, Forest Bend, Frozen Crossing, Volcanic Gate, Haunted Marsh, Desert Citadel, Crystal Caverns, Celestial Gardens and the Chaos Realm — with goblins, brutes, wolves, trolls, drakes, golems, armoured units, flying units, elites and world bosses arriving in combinations that shift as you go. Coins, gems, XP, stars, achievements, a Tower Collection and an enemy Encyclopedia give you something to chase beyond the next level.
