Play Metal Max 2 Kai (Japan edition · Japanese) Online

After choosing the name of the main character in "From the beginning" and talking to everyone at Mado's bar, talk to Maria again to proceed with the introduction battle. Once you are ready to take action, your first goal is to check information and equipment in town, then head east across the desert to El Niño. While the enemies are strong, don't force them to annihilate them, use escape, and when you hear that Nile has returned to Mado during El Niño, activate the transport device and return home. After an overnight stay, you will receive a repaired buggy. From now on, replenish the armor tiles, check the number of bullets and loading capacity of the main gun, and then challenge for the bounty.

Use the cross button to move the person/tank and select menus and battle commands. Press A to talk/search/open field command/confirm, press B to cancel/return to previous screen. In battle, use the cross button to select attack, tools, escape, etc., and confirm with A. While riding a tank, select equipment such as main gun, secondary gun, S-E, etc., not for humans. Since this game is command-based, it does not progress during selection, and I cannot confirm the common assignment of START/SELECT/L/R in public GBA materials, so I am not making any assumptions.
