Hobo 4: Total War

Hobo 4: Total War is a Flash side-scrolling beat 'em up game developed by SeethingSwarm, the fourth installment in the Hobo series. After defeating police and SWAT in the previous chapter, the government sends the army to hunt Hobo, triggering total war. Players control Hobo to fight infantry, heavy soldiers and even tanks. It retains classic punches, kicks and gross special attacks such as puke and fart. You can pick up rifles, cannon shells and trash items as weapons. Three difficulty modes are available, with level passwords to unlock stages and skills directly. It features crude cartoon art style and larger-scale battles than earlier games. With strong dark humor, it is a highly popular classic Flash fighting game 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.
