Though, Boosted Booster is preferred in Robo Rumble, Boss Fight, and Super City Rampage, where speed is less beneficial. It can also be very useful to control, retreat, and reach a target in most 3v3 modes and special events. This can be compensated with his Plugged In Star Power or other speed boosts, as 8-BIT can fight the fast and long-ranged Brawlers with ease that he’s usually prone to in Showdown.
So dealing damage behind cover or from afar is recommended as the enemies won’t be able to hit him as easily. Due to 8-BIT's slow movement speed, dodging projectiles from other sharpshooters like Colt or throwers like Barley is difficult.
Also, note that this should be a last-resort action, as he depends on his booster quite a lot. Keep in mind, this won’t be effective against Penny, Jessie, Surge, Belle, or any other Brawler with mechanics that can deal damage to multiple enemies, as their projectiles won’t be fully blocked.
When 8-BIT is within 7 tiles of his Damage Booster, his movement speed is increased from 580 points to 720 points. "When 8-BIT is near his Damage Booster, he will plug in and have increased movement speed."
