Ok, this is kinda a mix from spawn shield, pass out and barbequer.
What about a shield that is like Robotic Crab 2.0 and Fly The Coop, that cover your spacecraft with it?
When the shield is in use, it can Repel Bullets From enemy, Can be used as a melee, and as a SHIELD.
It won’t take much space in screen, just the enough for cover your spacecraft and abit more.
Example about how the shield may look like:
Also keep in mind that this weapon can’t save u from enemy collision, u need to keep close, but without touching the enemy for properly use.
At Start, it will start small, and then increase to the size of your spacecraft.
