Progear

Progear, known as Storm of Progear in Japan, is a 2001 side-scrolling shooter video game developed by Cave and published by Capcom for arcades. Set in the fictional kingdom of Parts, players assume the role of children controlling a plane equipped with the titular propelling engine to overthrow the Metoruin sages and their new world order. It was the sixth shoot 'em up game from CAVE, their first horizontally oriented shooter, and their eighth video game overall.

Initially envisioned as a vertical-scrolling shooter and intended to be their last game, Progear was created by CAVE as a collaboration with Capcom and served as their first horizontal-scrolling shooter title, with bullet dodging and enemy destruction being the main focus while adapting the company's shoot 'em up gameplay style in a horizontal format but faced a problematic development cycle before its launch to the market. Though first released in arcades, the game was later ported to mobile phone platforms, each one featuring various changes compared to the original version and has since been re-released as part of the Capcom Home Arcade plug and play game system. The game was later included in the 2021 compilation Capcom Arcade Stadium.

Progear proved to be popular in arcades among Japanese players and garnered positive reception from critics since its inclusion on the Capcom Home Arcade system, with praise given to the anime-style steampunk visuals, gameplay and accessibility, though the music was criticized. It was CAVE's only horizontal-scrolling shooter until Deathsmiles in 2007.
