Game Mechanics Primer
Alpha Planet TD is built around readable threats, deliberate placement and adapting a compact loadout to each mission. This overview avoids mission solutions and unreleased balance values.
Towers and the route
Enemies travel along a winding route cut through each 2.5D platform world. Read the terrain, then place towers where their range covers bends, bridges and crossings. Tower roles include direct damage, area control and support. Upgrades strengthen a tower, while selling and rebuilding can rescue a poor position when a mission changes shape.
No single tower answers every threat. Shields, armour, speed, regeneration and other enemy behaviours reward mixed loadouts and timely counters. Wave information gives you a chance to plan before committing resources.
Synergy and adjacency
Placement is more than fitting towers beside the route. A synergy checks participating setup and payoff towers in adjacent lattice cells: one may slow, expose, or disable a target so another can exploit the opening. Shared coverage also lets several towers contest an important bend.
Strong layouts balance these combinations against coverage. Clustering everything in one place may create a powerful kill zone, but it can leave the rest of the battlefield undefended.
Commanders and Combat Perks
Commanders shape a loadout through persistent and equipped effects. Combat Perks are active tools used during a mission, so timing and targeting matter as much as selection. Together they support different strategies without replacing tower placement and resource decisions.
Endless Mode
Endless Mode is the long-form survival challenge: waves continue to escalate and test how well a build adapts after a normal mission would have ended. It is intended for endurance, experimentation and fair comparison, not as the starting point for learning the campaign.
Alliances
Alliances connect players on the same frontier. Members can work towards shared activities, contribute to group goals and compare alliance performance. Alliance membership and rewards are recorded by the server so shared progress remains consistent across devices.
