Time Caisis 4 Game Machine is a large-scale simulation game machine, a coin-operated stealth game machine. There are pedals in the body. The pedals are used to evade and shoot, and the game process is compact through tight time constraints. . The biggest feature of the Crisis Resolve series is the addition of “hidden” elements. There are pedals in the body, which can realize evasion and shooting by stepping on the pedals, and the tight time limit makes the game process compact. This game method not only makes the light gun shooting game possess a certain degree of strategy, but also changes the monotonous situation of the light gun game in the past, and is more in line with the situation of real gun battles. Many new concepts have been added to the series in the development process, but the hidden core system has not changed.
