Tetra Troopers

Overview: Tetra Troopers blends spatial puzzle mechanics with wave-survival strategy. You are the commander, tasked with fitting your units together, fending off waves, and keeping every trooper alive as the day unfolds.

DAY SHIFT — Tactical TD Puzzles

• Frontline grid: an 8x12 board where each turn you deploy fresh troops or select upgrades that affect the whole squad or individual units.
• Snap & Stack: drop block-based squads onto the grid and fill every space—no gaps allowed.
• Fuse to Survive: stacking matters; place units on top of each other. Overlapping a Medic with a Sniper can create a hybrid veteran unit with combined strengths.
• Biomes and progression: 8 Biomes introduce diverse threats, each biome housing 9 difficulty levels to climb through.
• Unit evolutions (in development): Level 3 units can merge into powerful new Elite configurations as the system is implemented.
• Resources from victory: defeating waves yields manpower, feeding your ongoing campaign and upgrades.

The day advances with a rhythm of quick deployments and strategic upgrades, demanding a balance between immediate defense and long-term team cohesion. Spatial awareness and perfect placement are your keys to survival.

RETURN TO BASE — Build, Prepare, Plan

The battlefield becomes a persistent 60x60 Home Base. In the afternoon you:

• Build, place, and upgrade structures to bolster defense and production.
• Deploy troops to inner and outer perimeters, linking your base to the frontline threats.
• Plan strategic responses: distract the enemy or guide them into your kill zones with careful layout and timing.

Your base endures beyond single missions, and every decision shapes future defenses and resource flow. The arrangement of buildings, defenses, and upgrades compounds over days, influencing how well you weather later assaults.

NIGHT SHIFT — Tower Defense

As night falls, the threat arrives. Choose a biome and a difficulty to set the incoming attack:

• Risk vs reward: take higher risks for bigger rewards or play it safe and stabilize your position.
• Autonomous combat resolution: once the attack starts, combat resolves automatically based on your daytime preparations.
• Post-battle rewards: equipment and supplies are scavenged after each assault, scaled to biome and difficulty.
• 8 Biomes across both modes provide continuously scaling challenge.

THE STORY

Behind the bright blocks lies a narrative campaign in development, featuring branching consequences and 3 planned endings. The color-coded blocks carry a story that evolves with your choices, and the evolving campaign promises meaningful impact on future missions and outcomes.
