Line Tower Defense: Endless TD

Line Tower Defense is an idle tower defense game about building a long line of towers, merging units, and improving your strategy between waves.

Place towers on the grid, earn gold, merge duplicates, and upgrade your defense while enemy waves move toward your base. Each run starts small, then grows into a full defense line with Machine Gun, Sniper, Rocket, Freeze, Tesla, Stun, Multishot, aura towers, and more.

Choose bonus cards during battle, survive boss waves, and use the Tech Lab to unlock permanent upgrades. Every run gives Tech Points, so even a failed defense helps your next strategy.

Build your own tower setup:
- Merge towers for stronger units
- Upgrade damage, range, attack speed, crit, splash, stun chance, and aura effects
- Unlock new tower branches in the Tech Lab
- Pick bonus cards and blessings during combat
- Fight normal enemies, fast enemies, tanks, flying enemies, elite bosses, and world bosses
- Restart runs to claim Tech Points and grow stronger

If you like strategy games, idle tower defense, base defense, merge games, roguelite upgrades, and wave survival, Line Tower Defense gives you a compact battle map with deep progression and fast decisions.

Defend the line. Upgrade the lab. Survive longer every run.
