Starfarer is an indy space combat kind of game, in 2D. It show that 2D still have a great fun value. It’s currently in an alpha state but you can have access to it if you preordered it. So far you only have access to a few scenario and random missions. I think that this game was developped by a one man team so far and while it’s very early in the development. The gameplay is a mix of action and tactic. If you make a mistake you can be owned easily by one groups of fighter that will strike you at the right time. Each ships has strong and weak point forcing you to adjust to you enemies and learn how to maximize your ship potential.
This game is also very easy to mod and for example the background is a custom image and i simply used it to replace the regular background as a test. So ultimately you can customize the game easily.
