BUILD THE LINE. EVOLVE YOUR ARSENAL.

Place towers freely on buildable terrain and create overlapping fields of fire. Use optional bonus hardpoints, cover multiple routes, and choose how each tower evolves. Melt armor, shatter shields, freeze formations, and intercept aircraft with combinations built for the threats ahead.

CONQUER TWENTY BATTLEFIELDS

Progress through 20 missions across 10 sectors, with different routes, battlefield mechanics, and enemy formations. Each sector pairs an introduction mission with a more demanding mastery mission. Fight through frozen expanses, industrial foundries, shifting rifts, and the final Singularity sector.

Choose Story, Standard, Veteran, Nightmare, or Apocalypse. Earn a separate victory medal for each map and difficulty, and pursue 48 achievements as you master the campaign and its toughest challenges.

TAKE COMMAND

Lead one of six commanders, each with a passive and two abilities. Use Astra's focused attacks, Nyx's control of dense formations, or another commander's strengths to support your defense. Time Flux Gates, choose Protocols during a run, and unleash Overdrive when the line needs a decisive burst of power.

BUILD MASTERY BETWEEN RUNS

Spend earned shards on three permanent mastery ranks for each of the 15 tower types. Improve damage, range, and firing cadence as you develop your arsenal. Daily and Weekly challenges use fixed rules.

COME BACK FOR A DIFFERENT FIGHT

Survive Endless, face Boss Rush, or adapt to Lockdown's two-tower restriction. Daily and Weekly challenges bring fixed rules to fresh attempts. Experiment in Bastion Lab, share challenge codes, and review compatible replays to refine your strategy.
