When I first booted this game up, I didn't get what all the fuss was about. It's low tech, with very simple graphics. But after I played a while, upgraded my ship, found new crew members, and journeyed deeper into the galaxy, I got it.
Different weapons work against different shield types. You can upgrade your ship with drones which can ward off missiles or attack an enemy ship. This is all presented in a simple manner, but the gameplay is very addicting. The game is perma-death, which keeps you on the edge of your seat.
