Robot plays similarly to its predecessor series Robot, but with various new features: Robot has the ability to dash along the ground at any time (which is very similar to the original slide move from the original, but with better accurate controlling), cling to walls and Wall Jump, and dash and jump at the same time, increasing his speed in the air. This all gives Robot more mobility than his Classic counterpart; these modifications make it easier to go through the majority of the game without using any other gun than the default, which is different from previous Robot games where players were more inclined to rely on weapons won in previous fights against boss characters in previously conquered stages.
Robot is also able to locate capsules that permanently upgrade a part of his armor, such as his helmet, boots, chestplate, or arm cannon. An upgrade common to each game is the ability for Robot to charge weapons earned from bosses, which gives them an enhanced secondary fire mode. In later games, there are multiple armor types available that can either be mixed and matched, or completed for additional armor set bonuses.
