Killer Instinct
杀手本能
Killer Instinct is a one-on-one fighting game developed by Rare and released in arcades in 1994. Players choose from a roster of fighters—including Glacius, Sabrewulf, and Fulgore—and battle through a series of opponents to reach the final boss. The game uses a six-button layout and introduces a combo system built around auto-doubles and linkers, rewarding players who chain long sequences of hits. A distinctive feature is the two-tier health bar: depleting the first bar triggers a brief combo-breaker opportunity before the second round of fighting begins. Special moves, Ultra Combos, and No Mercy finishing moves add variety to matches. The arcade cabinet delivered pre-rendered 3D character graphics and a dynamic soundtrack that changed during combo sequences.
