Hazard Heights is a free online vertical action game where you guide your character upward through a gauntlet of enemies, racing against your own survival instincts to reach the getaway car at the top. Aliens, zombies, and fast-moving obstacles zip horizontally across the screen, and one wrong move ends your run instantly. The core mechanic is simple – move up, dodge everything – but the difficulty ramps hard and fast.

Early levels funnel you through narrow corridors that offer brief moments of cover, but the game quickly strips those away and throws you into wide-open chaos where every pixel matters. Timing your movements between enemy patterns is the key to posting a high score. There are no power-ups to bail you out, no checkpoints to fall back on – just your reflexes and pattern recognition. Each attempt teaches you something new, which keeps the 'one more run' loop going strong.

Hazard Heights is perfect for fans of reflex-based arcade games, vertical scrolling challenges, and score-attack titles. If you enjoy free car racing games with a twist, zombie survival arcade games, or alien obstacle courses, this one delivers a surprisingly deep challenge in a compact package.
