attack all enemy soldiers who appear by shooting them with their handgun as they would in any other light gun shooting game. The bottom of the screen indicates the player's remaining health, as well as their remaining ammunition, both which can be replenished by picking up power-up items hidden inside weapon crates. The player can also shoot at certain oil drums to kill all on-screen enemies at once. These segments end when the player reaches the entrance of the base. Maze mode When the player completes a Gun-shooting segment, the game switches playing style again, this time to a first-person exploration mode. In this mode, the player must navigate their character throughout the interior corridor of an enemy base to obtain vital items, including additional ammunition and health-restoring rations, while avoiding traps. Sometimes, the player will encounter their ally Spider, who will offer player information on how to complete their objective. When the player encounters enemy soldiers in these, it switches to a gun-shooting mode similar to the gun-shooting segments until all enemies are defeated. After the player has gotten what they needed to complete their mission, they must leave the base from where they began. The bottom part of the screen displays the player's map (which shows the areas that have been explored and the player's current position), their remaining health and ammo, and all the items they have collected. Regional differences The Japanese Family Computer version, Gun Sight, includes a password feature that allows the player to begin at later missions. In contrast, the American NES version increased the number of continues from three to five and allows the player to adjust the starting number of lives from the default three to five. The Japanese version did not include support for the LaserScope, only allowing the player to use the standard controller or the Famicom's light gun.
