Lava pits, spike traps, and poison swamps: the level itself trying to kill you alongside everything else.
Environmental hazards are dangers built into the game world rather than attached to enemy characters. They include static threats (spike pits, lava floors, laser grids), dynamic threats (rising water, moving platforms over death drops, collapsing structures), and persistent area effects (poison swamps, extreme cold, radiation zones). Good environmental hazards create spatial puzzles layered on top of combat: you're dodging enemies while also navigating around bottomless pits. They add variety to encounters without requiring new enemy types and teach players to read the environment as carefully as they read enemy behavior.
Example
Dark Souls' Blighttown is infamous for layering environmental hazards: narrow catwalks over fatal drops, toxic dart shooters, and a poison swamp at the bottom that became a FromSoftware trademark. Mega Man stages are defined by their environmental hazards, with each level introducing a unique gimmick (disappearing blocks, instant-death spikes, conveyor belts) that pairs with enemy placement. Spelunky randomizes hazard placement every run, turning environmental awareness into a core survival skill.
Why it matters
Environmental hazards turn level geometry into an active threat, making navigation itself a form of gameplay. They create memorable locations defined by their dangers and add challenge variety that keeps combat encounters feeling fresh even when enemy types repeat.
