Demon Front (Chinese: 魔域戰線; pinyin: Móyù Zhànxiàn) is a side-scrolling run and gun arcade game released in 2002 by International Games System.
[1] The gameplay is similar to Metal Slug and other run and gun games, but it lacks the vehicles that were an element of Metal Slug.
Each of the four characters brings along a pet, which can be sent to attack enemies or used as a shield.
Holding the shoot button charges the player's pet, and when released the pet launches a stationary devastating attack for a few seconds.
Characters include Jake and Sara, two regular humans from Earth.
