Space Cowboy Online (SCO), also known as ACE online and Flysis in other countries, is a free-to-play, client-based MMORPG with the characteristics of both Third-person shooters and flight simulators. In Space Cowboy Online, players pilot their own individual starfighters (called "Gears") throughout a number of maps, including terrestrial, lunar, and space maps. It has typical MMORPG elements such as leveling, currency, and a skills system. Space Cowboy Online is a largely Player vs. Player (PvP)-oriented game, with character leveling and item acquisition achieved through combat against Non-Player Characters (NPCs) and the completion of missions. As a player gains levels, more and more maps become accessible. Although a high level character will have better character attributes than most other players, no one at any level is invincible against other players in PvP. As in other MMORPGs, players can trade items, customize their gears, form parties ("formations") and guilds ("brigades"), and fight with other players via PvP combat. Almost all of the combat in Space Cowboy Online is aerial, from the third-person view. Players have the option to use the in-cockpit, first-person view by pressing on the "Delete" key once.
