Buy Flux Tower Defense PC Key

Where to buy Flux Tower Defense at the best price? As of 1 Sept 2026 this title has one offer, £5.29 at Steam. On PC that is the usual case, because only about one title in four gets a keyshop offer and the rest stay with the platform store. There is nothing to compare, but we track this price daily and show how it stands against earlier readings, and a price alert will tell you about any drop. On PC you buy a key that you activate in Steam or another client, and this is the widest market we track, with more than a quarter of games carrying a keyshop offer.

About Flux Tower Defense

Flux Tower Defense - about the game
Flux Tower Defense

Stop every wave, or lose the run. Enemies erupt from the red portal. Your fortress — teal, glowing, alive — is the only thing between the map and extinction. One death wipes your save, so every tower placement counts.

Elemental attributes, layered deep

Every tower levels from 1 → 15 with branching milestones:

  • Lv 5 rolls a random element: LAVA (burn DoT), GLACIER (slow), ELECTRIC (chain), or STEEL (crit).
  • Lv 10 upgrades that element to Tier 2 — a unique ability. LAVA burns hits for 25% dmg/s over 3s. GLACIER has a 20% chance to freeze. ELECTRIC jumps to nearby enemies. STEEL lands 2× crits.
  • Lv 15 rolls a second attribute, stacking two elements on one tower. The combos run deep.
Place. Sell. Reshape.

Towers block the path. Traps walk over. A* pathfinding recomputes the instant you sell, so mid-wave repositioning is a real tactic — kite elites into your choke, open a shortcut, swap a Lv 10 into a Lv 1 at the front line when the money calls.

Endless waves, boss rotation

Wave 1 is a tutorial of Slimes. Wave 2+ drops a boss variant of a random species at the end of every spawn queue — 5–10× HP, larger, meaner. 13+ enemy types each have dedicated mechanics you'll learn the hard way.

Compete on Steam Leaderboards
  • Highest Wave — all-time global ranking
  • Fastest Wave 20 — speedrun the first 20 waves
  • Weekly High Score — a fresh board every week
28 Achievements — depth at every tier

Progression, Mastery, Attribute, and Fun categories. Challenge runs include Minimalist (5 towers to Wave 20), Eggshell (no walls to Wave 15), Sommelier (all four Tier 2 attributes in one run), Endless Maze (enemy path 60+ cells), and Close Call (10 waves cleared at 1 life).

Live tools: damage meter + enemy bestiary
  • Damage Meter — click the Σ icon to see which tower is carrying your run.
  • Enemy Bestiary — locked until first sighting, each entry explains the mechanic.
  • Game-over summary — survived time, kills, top damage dealers, attributes rolled, and a Personal Best badge on a new high wave.
Steam integration
  • Steam Cloud — saves, progress counters, and settings sync across all your devices.
  • Steam Rich Presence localized in 14 languages.
  • Steam Timeline — every wave clear and death lands as a clip-worthy moment.
Built-in accessibility
  • Color Blind Assist — attribute glyphs + text labels on every tower so color alone is never load-bearing.
  • Reduce Motion — calms portal rotation, fortress pulse, damage shake, and UI glow animations.
  • Mouse-only play — pause button on the HUD, every action reachable without the keyboard.
  • Independent volume controls for music and SFX, with a global mute.
Aesthetic — zero image assets

Every enemy, tower, effect, and UI element is rendered in pure Canvas 2D. Portal triangles rotate. Fortress shields peel off as life drops. Wall towers auto-tile into crenellated battlements. Lv 15 dual-attribute towers shimmer with two elemental colors. No PNG sprite sheets. No pre-rendered tiles. Just code painting pixels every frame.
