Your ship WILL NOT regenerate or fix itself during a battle unless you have found the necessary powerups during the battle.
Examples of powerups that can restore you are:
Repair Droids - restore your hull points
Energy Reserves - restore your shield points
And the “Cheese” - we’ll leave this one for you to find out.
These are vital for staying healthy in intense battles or avoiding regular near-death situations lurking within the Battle Royale arena.
