wavebased

Wavebased, also written wave-based, refers to a game mode or design pattern in which players confront a sequence of enemy waves. Each wave is a discrete combat round where enemies spawn from one or more points, with escalating difficulty, rewards, and resource constraints. Waves progress until a fixed number of rounds is completed or a final boss wave is defeated; failure to complete a wave ends the run or incurs penalties, depending on the game.

Mechanically, spawning is controlled by wave index, spawn rate, and enemy mix. Difficulty scales through more enemies, tougher variants, or increased AI aggression. Between waves, players may earn currency, ammo, or equipment upgrades, and may perform objectives or fortify defenses. Some modes include environmental hazards, randomization, or boss waves to punctuate progression.

Variants are common in cooperative PvE experiences and are often labeled Horde or Survive modes. They differ from endless or time-limited modes; endless variants repeat waves with increasing difficulty until players are overwhelmed, while finite variants have a predetermined set of waves. Designers balance wave composition, pacing, and resource economy to maintain challenge without frustration, and consider randomness to boost replayability while preserving fairness. Clear failure states and feedback help players understand progression and planning.

Examples include Gears of War's Horde mode, which popularized the concept in mainstream gaming, and Killing Floor's wave-based survival with boss waves and loot rewards.
