Shoot 'em Up
The most-used genre word in the British computer press
The dominant action genre of the 8- and 16-bit era: fly, shoot, dodge, repeat. From Space Invaders through R-Type and Uridium to the bullet-hell descendants, and the term the period press reached for more than any other.
The shoot ’em up is the defining action form of the home-computer era. The player pilots a ship or figure, enemies arrive in patterns, and survival depends on reading those patterns while returning fire. Everything else — scrolling direction, weapon systems, power-up economies — is variation on that core.
Its grip on the period is measurable. Across the magazine archive it is the single most-used genre term in the British computer press, appearing on some 16,000 pages in over 4,600 issues. Reviewers assumed it as the default: a game was a shoot ’em up unless it was something else.
The spelling was never settled. Shoot ’em up, shoot-em-up, shootem-up and shoot ’em-up all appear, often within one magazine and occasionally within one review.
Fast facts
- Core loop: move, fire, avoid, survive the wave.
- Perspective: vertical or horizontal scrolling, or fixed-screen in the earliest form.
- Skill model: pattern memorisation over reflex alone.
- Defining titles: Space Invaders, Defender, Gradius, R-Type, Uridium.
- Period status: the assumed default genre in British reviews.
Genre conventions
- Waves and patterns: enemies arrive in choreographed formations, not randomly.
- Power-up economy: collected upgrades that are lost on death, making recovery hard.
- The end-of-level guardian: a large, multi-part enemy with a weak point.
- One-hit death: common on home machines, softened by shields on later titles.
- Scroll lock: the playfield moves whether the player does or not.
Sub-forms the period distinguished
- Vertical scroller: Xevious, Raiden.

Evolution
- 1978-82: fixed-screen origins in the arcade, ported everywhere.
- 1983-87: scrolling becomes standard; the home conversion is a critical battleground.
- 1988-92: 16-bit machines deliver arcade parity; R-Type on the Amiga is a landmark.
- 1990s onward: the form narrows into the enthusiast “bullet hell” tradition.
