Fortify: Tower Defense

Fortify is a tower defense strategy game where your plan, not luck, decides the battle. Enemies march down a winding road toward your fort. Build towers beside it, upgrade them, send in a hero and hold the line through ten waves, with a dragon boss at the end of every map.

FOUR TOWERS, TWO UPGRADES EACH
• Volt: rapid fire, the backbone of an early defense
• Pierce: heavy long-range shots that go straight through armor
• Ravager: splash damage along the road for crowds
• Glacier: slows everything it hits
Sell any tower for 70% of what you spent on it and rethink your defense mid-battle.

FOUR HEROES, FOUR SKILLS
Choose a hero for each battle. It costs no gold, cannot be defeated and goes wherever you move it. Fire burns, Ice slows, Nature strikes fast and Rock hits hard. Each hero has one big skill (Firestorm, Deep Freeze, Bramble Surge or Earthshatter) that you can use twice per battle, 40 seconds apart.

EIGHT ENEMY TYPES, TEN WAVES
Slimes, skeletons, bats, goblins, spiders that slow your towers' fire, armored orcs, golems and the dragon. From wave 3, red Enhanced enemies come tougher and faster. From wave 6, gold Elites join them, twice as tough. Both pay more gold.

SIX MAPS, THREE STARS
Six campaign maps, each with its own winding road and biome: meadow, forest, rocks, snow, desert and embers. Win with 4 or more lives left for three stars. Every win unlocks the next map.

STRATEGY, NOT LUCK
No random critical hits and no hidden dice. The battle is fully deterministic, so the same defense always plays out the same way. If your fort falls, a better plan can win.

DAILY SIEGE
A new battle every day, with its own map and modifier. Win day after day to build your streak.

MADE FOR ONE HAND
Portrait play, tap or drag to build, three speeds (1x, 1.5x, 2x), pause, and an early call for the next wave for bonus gold. Leave mid-battle and continue later. How to play and the rules are one tap away on the home screen.
