Oil

In Outlander, players must constantly monitor their dashboard gauges, as depleting this resource entirely forces them into dangerous on-foot combat against road raiders. The substance is typically scavenged from abandoned roadside structures or purchased in settlements using earned credits, serving as a primary driver for the game's economy and exploration loop.

Within the One Piece: Grand Battle franchise, the item transitioned into a tactical tool for arena control. In the debut One Piece: Grand Battle game, players can shatter barrels containing the liquid to coat portions of the battlefield. This allows characters to slide quickly across the arena to initiate combos or evade enemy attacks, integrating environmental physics directly into the combat system. Similarly, in Tweety's High-Flying Adventure, the substance is placed near key collectibles, requiring players to carefully time their jumps to avoid momentum loss. Across these releases, the item demonstrates how a single concept evolved from a strict survival resource in early 1990s action games into a dynamic physics modifier in 2000s platformers and fighting games.
