About this game

⚔️ MERGE. DEFEND. EVOLVE.

Merge Defense blends the best of merge games and tower defense into an addictive
roguelite. Summon towers, drag them together to fuse more powerful weapons, and defend
your core wave after wave.

🔮 THE POWER OF FUSION
Merge two matching towers to level them up, or fuse different types to discover 15 named
hybrid towers: Blizzard, Devastator, Lethal Cloud… each with its own identity and effects.

🗺️ A JOURNEY ACROSS 6 WORLDS
Forest, Desert, Snow, Volcano, Hive and Void. Every biome changes the rules and hides a
unique BOSS with its own mechanic: one regenerates, another shields its allies, another
takes shortcuts to your core…

🎯 ROGUELITE DEPTH
• Relics that transform your run
• 8 commanders with distinct playstyles
• Active abilities, evolutions and special tiles

♾️ MODES FOR DAYS

• ENDLESS: a never-ending journey that shifts biomes as you go
• Boss Rush, Daily Challenge and Contracts to raise the stakes

✨ AND MORE
• 100% offline: play anywhere, no connection needed
• No abusive timers: your skill decides
• Handcrafted neon pixel-art

Enemies that force you to adapt, memorable bosses, and a core loop that hooks you.
How far can you get?

Merge, adapt, survive.
