zombie-escape 0.8.2

Top-down zombie survival game built with pygame.

Zombie Escape

The city is overrun with zombies! You fled the horde, taking refuge in an abandoned factory.

Inside, it's a maze. They won't get in easily. But you have no weapons. Night has fallen. The power's out, plunging the factory into darkness.

Your only tool: a single flashlight. A car... somewhere inside... it's your only hope.

Pierce the darkness and find the car! Then, escape this nightmare city!

Overview

This game is a simple 2D top-down action game where the player aims to escape by finding and driving a car out of a large building infested with zombies. The player must evade zombies, break through walls to find a path, and then escape the building in a car.

Controls

• Player/Car Movement: W / ↑ (Up), A / ← (Left), S / ↓ (Down), D / → (Right)
• Enter Car: Overlap the player with the car.
• Quit Game: ESC key
• Restart: R key (on Game Over/Clear screen)
• Window Scale (title/settings only): [ to shrink, ] to enlarge

Settings (Title Screen)

Open Settings from the title to toggle gameplay assists:

• Footprints: Leave breadcrumb trails so you can backtrack in the dark.
• Fast zombies: Allow faster zombie variants; each zombie rolls a random speed between the normal and fast ranges.
• Car hint: After a delay, show a small triangle pointing toward the fuel (Stage 2 before pickup) or the car.
• Flashlight pickups: Enable flashlight spawns that expand your visible radius when collected.
• Steel beams: Adds tougher single-cell obstacles (5% density) that block movement; hidden when stacked with an inner wall until that wall is destroyed.

Game Rules

Stages

At the title screen you can pick a stage:

• Stage 1: Find the Car — locate the car and drive out.
• Stage 2: Fuel Run — find a fuel can first, pick it up, then find the car and escape.

An objective reminder is shown at the top-left during play.

Characters/Items

• Player: A blue circle. Controlled with the WASD or arrow keys.
• Zombie: A red circle. Will chase the player (or car) once detected.
  • When out of sight, the zombie's movement mode will randomly switch every certain time (moving horizontally/vertically only, side-to-side movement, random movement, etc.).
• Car: A yellow rectangle. The player can enter by making contact with it.
  • The car has durability. Durability decreases when colliding with internal walls or hitting zombies.
  • If durability reaches 0, the car is destroyed, and the player is ejected.
  • When the car is destroyed, a new car will respawn at a random location within the stage.
  • After roughly 5 minutes of play, a small triangle near the player points toward the objective: fuel first (Stage 2 before pickup), car after fuel is collected (Stage 2), or car directly (Stage 1).
• Walls: Outer walls are gray; inner walls are beige.
  • Outer Walls: Walls surrounding the stage that are nearly indestructible. Each side has at least three openings (exits).
  • Inner Walls: Beige walls randomly placed inside the building. Inner wall segments each have durability. The player can break these walls by repeatedly colliding with a segment to reduce its durability; when it reaches 0, the segment is destroyed and disappears. The car cannot break walls.
• Fuel Can (Stage 2): A yellow jerrycan. Pick it up before driving the car.
• Flashlight: Picking one up boosts your visible radius by 35%.
• Steel Beam (optional): A square post with crossed diagonals; same collision as inner walls but with triple durability. Spawns independently of inner walls (may overlap them). If an inner wall covers a beam, the beam appears once the wall is destroyed.

Win/Lose Conditions

• Win Condition: Escape the stage (level) boundaries while inside the car.
  • Stage 2 also requires that you have collected the fuel can before driving out.
• Lose Condition:
  • The player is touched by a zombie while not inside a car.
  • (Note: In the current implementation, the game does not end immediately when the car is destroyed. The player can search for another car and continue trying to escape.)
