Pixel Defense

About Pixel Defense

Pixel Defense is the only game on the site with a genuine strategic layer. You aim and fire with the pointer, defending a base at the bottom of the screen from waves that descend from above. That part is straightforward action. The part that makes the game is what happens between waves: you are offered three upgrades drawn from a pool of eleven, and you must take exactly one.

Those choices compound. An early economy upgrade — faster reload, wider spread — pays dividends for the rest of the run. A late power upgrade — piercing shots, splash damage — is worth more at the point where individual enemies have enough health to matter. Taking them in the wrong order is the most common reason a run ends at wave 8 rather than wave 15, and it is a strategic mistake rather than an execution one.

The base has fifteen health and does not regenerate, but a single upgrade in the pool restores five. Whether to spend a choice on repair or on capability is the game's recurring dilemma, and there is no universally correct answer — it depends on your health, your current build, and how many waves you think you can still reach.

How to Play

Keep your base alive through as many waves as possible, spending each between-wave upgrade choice wisely.

Every game on this site can be paused with P or Esc and restarted with R. Sound, retro screen effects and fullscreen are toggled from the buttons above the play area.

Game Mechanics

The upgrade pool

Eleven upgrades across three families. Economy: reload speed, projectile speed, and a second barrel. Power: piercing, splash, and damage. Utility: base repair, a temporary shield, slow field, extra score multiplier and a wave skip. You are offered three at random after each wave and must take one — you cannot decline.

Enemy composition

Five enemy types with different health, speed and behaviour, including one that splits on death and one that heals nearby allies. Wave composition is drawn from a budget, so a wave might be many weak enemies or a few tough ones — and the correct build differs between those cases.

Aim-and-hold firing

You fire continuously toward the pointer at your current reload rate. There is no ammunition. The skill is entirely in target prioritisation, because your damage output per second is fixed and choosing the wrong target is the same as not firing at all.

Tips & Strategy

• Take reload speed first, almost always. It multiplies everything else you will ever take. Compounding upgrades belong early.
• Kill healers before anything else. A healer left alive makes every other enemy in the wave take longer, which is the same as reducing your damage output.
• Save repair for when you are below eight health. Taking repair at thirteen health wastes most of it. It restores five, not to full.
• Do not take splash before you face grouped waves. It is excellent against many weak enemies and nearly worthless against three tough ones. Read the wave preview.

Common Mistakes

• Taking damage upgrades early. Early enemies die in one or two hits regardless. Extra damage does nothing until enemy health grows.
• Shooting the nearest enemy. Nearest is rarely most dangerous. Prioritise by time-to-base and by whether the enemy is making others harder to kill.
• Hoarding health. Base health you never spend is wasted. Being at fifteen health when the run ends means you were playing too cautiously to build.
