This is an early look at outer space battles in Star Explorers. I am adding asteroids and hostile UFOs. Asteroids drop ores and possibly other materials when you destroy them. UFOs shoot back at you, and you will be able to board them after you disable them.
These features will be available in the next major update. I don't have a specific date set for this, but hopefully in the next month or two.
