Hobo: Prison Brawl

Hobo: Prison Brawl (also known as Hobo 2) is a Flash side-scrolling beat 'em up created by SeethingSwarm and released in 2009, the second entry in the Hobo game series. Following the events of the first game, Hobo gets arrested and locked inside prison. He must fight his way out through jail cells, mess halls and prison corridors. Control Hobo to battle inmates, prison guards and riot cops. Start with basic punches and kicks, build combo meter during fights to unlock gross special attacks such as puke and spit. You can also grab environmental objects like food trays as weapons. It features crude cartoon art style and dark humor, swarms of enemies and fast-paced combat. It is a famous nostalgic Flash browser game popular on Chinese mini-game portals.

These games get the keyboard directly — the controls are whatever the game itself defines, usually in its own help or options screen. Some games show on-screen buttons on phones.
