Minimal Bastion

DESCRIPTION

Minimal Bastion is a colorful geometric tower-defense game about building specialized defenses, adapting to changing threats, and holding the line across four distinct arenas.

Command 10 towers, each with branching upgrades and specialized roles. Set targeting priorities, combine towers into effective kill zones, and use Pulse Plates, the Charge Forge, Protocols, and arena-specific mechanics to respond when your original plan is no longer enough.

Each arena features its own layout, economy, and enemy progression:

• Survive a 20-wave campaign
• Continue through 10 harder Mastery waves
• Push into generated Endless waves
• Choose from four difficulty levels and multiple challenge directives
• Experiment freely in Sandbox mode

Enemies include armored, shielded, regenerating, elite, support, and boss threats that require different defenses rather than a single universal strategy.

SOLO & TWO-PLAYER CO-OP

Play solo or defend together in private two-player online co-op. Players share credits, lives, towers, upgrades, targeting, and tactical systems, with both players able to control the entire defense.

Co-op in the Windows version currently uses a direct TCP connection on port 28741, so internet hosts may need port forwarding or a peer VPN such as Tailscale or ZeroTier.

BROWSER DEMO

The browser version is intended as a convenient single-player demo and does not include online co-op. It also has some mild graphical and performance reductions compared with the native version.

For the complete experience, the downloadable Windows version is recommended.

KEEP PUSHING

The Tactical Library documents towers, upgrades, enemies, status effects, and game systems as you discover them. Run History, medals, achievements, and career records track your progress across difficulties, directives, Mastery, and Endless play.

Minimal Bastion is currently a free public playtest. Feedback on balance, clarity, co-op reliability, and the strategies that emerge is welcome.
