Mecha Fortress: Robot War TD Mod APK

Your tower is a mech. Your weapons are cards you draft mid-battle.

Mecha Fortress is an idle tower defense strategy game built on a roguelike draft. Endless waves of robot enemies come down one lane. Your mech sits at the bottom and never moves. What it fights with is decided between waves, three cards at a time.

⚙️ TOWER DEFENSE, DRAFTED MID-BATTLE
Twenty waves to a stage. Bosses keep no schedule and can arrive while you're still building.
Between waves you draft new tech: a turret for an empty mount, a damage boost that costs fire rate, an elite card that rewrites a weapon. Three cards, one pick. Or spend a die and reroll the offer.
Survive the stage, hold your armor above half, finish untouched. Three stars, three chests.

🔧 BUILD YOUR DEFENSE
Pick your mech's main gun, then unlock more weapons as you go. Every other turret arrives mid-fight, one card at a time, from the loadout you brought.
Between runs you swap mechs, recruit pilots, and upgrade a technology tree that unlocks as your mech levels.
Gems socket into your pilot's equipment and shift what the machine is good at. Damage comes in elements and enemies resist them differently, so the build that melted the last stage can stall on the next.

🏺 COLLECT ARTIFACTS
Artifacts turn up in pieces: a trench lighter, a plague mask, a chess king, a lucky paw. Junk somebody died carrying. Complete one and it works forever without taking a slot. Feed it shards and it gets stronger.

☠️ HUNT THE DEVOURER
A daily challenge: one boss, one day to break it. Everyone who fights it lands on the same leaderboard, ranked by shield layers torn off. The modifiers change at midnight, and so does the answer. After each attempt you keep one of three Deploy Cards for the next run. Stack up to nine.

🌙 IDLE TOWER DEFENSE, OFFLINE PROGRESS
Your base keeps working while the game is closed. Mines and generators fill up offline, and patrols bring in resources while you're away. Come back, collect, upgrade, go again.
Auto battle and auto advance run the tower defense for you, so combat carries on when you'd rather watch than tap.

❓ FAQ
Is it free to play? Yes, the full tower defense campaign is free.
What happens when I close the game? Your base carries on without you. Mines, generators and patrols keep producing offline, and it's all waiting when you come back.
Is there real strategy in it? Draft order, element matchups and upgrade priority decide whether you survive. The tactics change with every card you're offered.
Does it run out? No. The campaign loops endlessly, and hard mode, the Insect Hive and the daily boss challenge keep going.
How is it different from other tower defense games? You don't place towers on a map. You draft them mid battle, so every run builds a different machine.

Love tower defense, roguelike strategy, idle games, sci-fi survival and dieselpunk mechs? Mecha Fortress is all five, and a run fits in a coffee break.
