How to play PIXFORTRESS DEFENDER

PIXFORTRESS DEFENDER is a retro defender game: you stand beside a fortress on the left, shoot invaders marching in from the right, and survive as many waves as you can. This guide explains the controls, enemies, combos, bosses, and a few tips to help you last longer.

Objective

Stop enemies before they reach the fortress wall on the left. Each one that gets through costs you a life and can weaken your weapon. When all five lives are gone, the fortress falls and the game is over. Try to get the highest score and reach the furthest wave you can.

Getting started

Open the game and click on it so it picks up your keyboard.
Press ENTER on the title screen to start wave 1.
Hold SPACE to shoot. Move with the arrow keys or W / S.
Press H on the title or game-over screen for a quick reminder of the controls.

The game works best on desktop with a keyboard. No download or account is required.

Controls

UP / DOWN or W / S — Move up and down
SPACE (hold) — Shoot
ENTER — Start the game or play again after game over
P — Pause and resume (press any key to resume)
M — Turn sound on or off
H — Open or close the help screen (title and game-over screens only)

What's on screen

Along the top of the game you will see:

SCORE — Your points this game (combos increase what you earn)
WAVE — Which wave you are on; each wave gets a little harder
Combo bonus — Shows ×1.5, ×2, or ×3 when you are on a kill streak
Yellow squares — Your weapon level (1 is weakest, 5 is strongest)
Hearts — Lives left (you start with 5)

Beside the game, the TOP 10 list shows your best scores and how far you got. Beat the top score and you get a confetti celebration.

Enemy types — the glitches

The invaders are glitchy pixel creatures that differ in speed and toughness. Deal with the fast ones first.

Basic glitch

The standard cyan glitch. One shot to destroy. Moves at a steady pace. Worth 100 points. Appears from wave 1.

Swift glitch

A small yellow glitch that moves about twice as fast as the basics. One shot, but easy to overlook. Worth 150 points. Appears from wave 3.

Flying glitch

Moves up and down as it advances, so it is harder to hit. One shot. Worth 135 points. Appears from wave 2.

Tanky glitch

A bigger, armoured glitch that needs three shots to destroy. Slow but tough. Worth 320 points. Appears from wave 5.

Weapon upgrades

Your crossbow fires more bolts as your weapon level goes up — shown by the yellow squares at the top. At level 1 you fire one bolt; at level 5 you fire a wide spread of up to five.

Pick up yellow gift boxes that drift in from the right to raise your weapon level by one (up to 5). You can shoot a box to collect it too.

Gift boxes appear at random during normal waves, usually early in the wave. Beating a boss always leaves a weapon upgrade behind.

Extra lives

Rare red boxes with a white heart give you one extra life, up to a maximum of five. If you are missing lives at the start of a wave, there is a small chance a heart box will appear that wave. Grab them when your fortress is taking a beating.

Combo scoring

Kill enemies one after another without a long gap and your score gets multiplied. Each kill resets the clock; if you go 4 seconds without a kill, the streak ends.

3 kills in a row → ×1.5 points (green)
6 kills in a row → ×2 points (magenta)
10 kills in a row → ×3 points (yellow)

Hit a new combo level and you will see a small flash on screen. If an enemy reaches the wall, your combo resets — so defending the fortress helps your score as well as keeping you alive.

Boss waves

Every 5th wave (5, 10, 15, and so on) is a boss wave. Normal enemies stop appearing; instead, a boss walks in from the right. Each one looks different and has a random name (for example, GLITCH TITAN or NEON LORD).

The shield

Bosses arrive with an energy shield. While the shield is up, your shots only weaken the shield — not the boss. Keep shooting until the shield breaks. Then the boss gets angry and moves faster.

Beating a boss

Once the shield is gone, your shots hit the boss directly. Keep shooting until it is destroyed. You earn a big points bonus — more on later waves — and a weapon upgrade is left behind. Bosses are the best way to get your weapon level back up in the later waves.

If a boss gets through

A boss that reaches the fortress hurts much more than a normal enemy. On later waves it can take several lives in one go and drop your weapon level by up to three. Do not let bosses through.

Fortress damage and lives

You start each game with 5 lives. When a normal enemy reaches the wall:

You lose 1 life
Your weapon level drops by 2 (but never below 1)
Your combo resets
The fortress looks more damaged

When you run out of lives, the fortress collapses and the game ends. Press ENTER to try again.

Waves and difficulty

Clear every enemy in a wave and, after a short pause, the next wave begins on its own. Later waves bring more enemies (up to 15 at once), send them faster, and mix in tougher types. There is no final wave — see how far you can get.

Scoring and leaderboard

You earn points for each enemy you destroy; combos boost what you score.
Bosses are worth the most points.
The top 10 list saves your best score and the wave you reached.

Tips

Shoot the fast ones first — they reach the wall quickly if you ignore them.
Start on tanky glitches early — they need three shots, so give yourself time.
Keep your combo going — even a ×1.5 bonus adds up over a long game.
Grab gift boxes before they leave the screen — they drift left and vanish.
Move up and down for flying glitches — let basic glitches die on your usual line when you can.
Fight bosses in two steps — break the shield first, then focus fire when it speeds up.
Press P to pause if you need a break — nothing happens while the game is paused.
Click the game window if the keys stop working.
