How to Play SD Keiji Blader
Quick start
In the galaxy, talk to Milly, the Doctor, and Stakov using A, then talk to Milly again to ask her to accompany you. When you get off to the ground, go to the nearby "Shinjuku". Listen to Reiko at the doctor's house and head for the research institute to the north. It's safe to open the command with B and check your equipment and recovery methods in "Items" before heading out.
Controls
Directional keys: Move the main character or cursor. A: Talk, research, decide on items. B: Open command on map, cancel item. Use the command ``Change'' to transform or cancel, ``Item'' to use or equip, and ``Unit'' to select the ability to use UE. You can increase your movement speed by pressing B while riding the Turbo Gear and Sky Gear that you obtain along the way.
SD Keiji Blader — About this game
It is a special effects hero-style adventure that departs from base Galaxy and visits towns such as Shinjuku and Nakano as well as enemy facilities. Battles are mainly one-on-one between the protagonist and the enemy, and companions may help with recovery and attacks. Use the equipment and recovery items you bought to prepare for strong enemies. Transformation can be performed using map commands, but just transforming does not give you an advantage in battle. The basic idea is to confirm your next destination through conversation and proceed while collecting tools related to the enemy's strategy.
