Metal Soldiers 4 Pro has temporarily become free on the Google Play store — a premium version of the mobile action game clearly inspired by classic arcade titles in the spirit of Metal Slug and Contra.
It is a two-dimensional run\'n\'gun in which players must fight their way through linear levels, shooting through waves of enemies, collecting power-ups, and battling various bosses. As they progress, new weapons are unlocked, and in certain segments players can control vehicles, including mech robots and tanks.
Metal Soldiers 4 originally launched on Android in August 2025 as a free-to-play game with ads and in-game purchases. Later, the Play365 studio released the Pro version — without ads or monetization. It normally sells for 75 rubles, but the developers have now made it completely free.
You can download Metal Soldiers 4 Pro directly via Google Play. The duration of the promotion has not been specified.
