About this game

Stellar Bastion is a space tower defense game where combining towers is the strategy.

Place lasers, cannons, tesla coils, slow fields, railguns, and missile towers across the battlefield. Position them next to each other, upgrade them, and unlock combo weapons: Plasma Cannons, MIRVs, Black Holes, Nukes, and more. Experiment with placement to discover every fusion.

WHY STELLAR BASTION
* A tower defense built around combos, not just stacking the same tower
* Easy to learn and deep to master. Every map is a fresh puzzle
* Pixel-art space battles with punchy impacts and screen shake
* No forced ads and no paywalls blocking strategy

TOWERS AND COMBO WEAPONS
* 8 tower types: Laser, Cannon, Tesla, Slow, Missile, Railgun, plus aura support towers
* Fuse neighboring towers into combo weapons like the Plasma Cannon, MIRV, Black Hole, and Nuke
* Three upgrade tiers per tower for chasing maximum power

9 UNIQUE MAPS
Battle across Canyon, Confluence, Crossroads, Fortress, Gauntlet, Pincer, Spiral, Vortex, and more. Each map has its own paths and choke points that change which combos win.

MODES AND COMPETITION
* Daily Challenge: a new layout every day, the same for every player
* Global Leaderboards: climb the rankings and prove your strategy
* Endless waves: see how long your defense can hold

HOW TO PLAY
1. Place towers along the enemy path
2. Cluster and upgrade them to trigger combo weapons

Think fast, build smart, and hold the line. Download Stellar Bastion and start combining.
