As the title clearly indicates, Prison Escape is an action game where your mission is to escape from a secure prison and gain your freedom once again. Your character is facing the death penalty "thanks" to a conspiracy against you, the role being to break out the prison before you get the punishment. Easier said than done. You will have to fight with other inmates to gain respect, become friends with others in order to get help, etc.
The gameplay contains a variety of missions which must be completed if you want to escape from this prison. In terms of controls, you can move the protagonist across the jail by using the virtual stick displayed at the left side of the screen, while various actions like running, stabbing, punching, heal, and more, can be performed by tapping the commands found towards the right side of the interface.
Some of them might vary depending on the availability of a specific weapon. For example, you won't be able to stab someone if you don't have a knife. You can't throw grenades if you don't have any, and so on.
