Biozone is a 2D side-scrolling STG type of small indie game published by KONAMI in 2010. It came with old-school retro graphics, exciting background music, and flexible character actions design. I believe players who like exciting will fall in love with this game, even if many years later.
Ultra Assault is an old, classic Raiden-style 3D flight shooting PC game released in 2003 with multiple high gaming difficulties. AppNee suggests it to Raiden series' fan players, you should not miss it.
At first sight of Broforce, I guess most players maybe think of one series of films + one series of video games: First Blood + Metal Slug. AppNee tells you, this is definitely not only a normal 2D pixel game, nothing can stop the crazy enthusiasm from vast majority of players to this game. BTW, IGN gave BroForce 8.8 scores of high praise.
Tank Force (ANA: タンクフォース, Tanku Fōsu) is the sequel of famous and classic Battle City shooter video game, released by Namco in 1991. For any video game fan, I believe you must have played Battle City on FC platform, which was quite a hot and popular game at that time.
Namco's Battle City for FC has always been one of the most classic and popular video games for most players. It not only can let players manipulate tanks to gallop battlefield, also enables players to defeat the powerful enemies through double cooperation using tactics.
