⬇ The Draw
Click ⬇ Draw to reveal 6 tower cards. Pick one to keep as a firing tower — place it on any open hex. The remaining 5 become free Scrap Walls you place to maze the enemy path.
⬆ Merging & Blueprints (Draw Phase)
Before placing, you can combine cards: two identical type+tier cards merge into the next tier. Certain combinations forge powerful Blueprint towers — look for the green combo buttons above selected cards. Open ⚗️ to see all recipes.
⚗ Forge Phase (Between Waves)
After each wave clears, a Forge Phase begins automatically. Click up to 4 towers already on the map to merge or forge them — no adjacency required. Click ⬇ Draw when you're done to start the next wave's draw.
🗺️ Mazing
Enemies always follow the shortest open path from IN → OUT. Place towers and scraps to force longer detours — more time in range means more damage. You can never fully block the path.
⚡ Power-up Tiles
Glowing tiles appear on the board each wave. A tower standing on a tile gains its buff during combat: ⚡ Speed (fires 35% faster), 🔭 Range (+40% range), or 💥 Damage (+50% damage).
★ Synergy & Auras
A tower with 2+ same-type neighbours gains +20% damage (gold ring). The 💎 Aetheric Engine stops firing and instead boosts all towers within 2 hexes by +60% damage.
⬆ Tower Quality
After wave 1, the ⬆ Qual button appears. Spend Gears to raise draw quality — higher levels shift your cards toward Tier 2, 3, and eventually Tier 4 towers.
⚙ Economy
Kill enemies to earn Gears. Every 5th wave is a Payday Round with 2× bounty. Click a tower or scrap on the map to sell it or view stats. The game goes on indefinitely — survive as long as you can!
