    Orbital Defense Force Available Now!

    Orbital Defense Force is now available to purchase! It’s hard to believe I’ve been working on this game for the past 3 and a half years. To everyone who has been following, Thanks. It’s been a long journey and I hope Orbital Defense Force is as fun for you as it is for me. I set out to make the game I wished was created and I’m proud of how it turned out. Again, thanks for all the support. It means the world. P.S. Adding the steam launch option ‘ --morePlayers ‘ allows lobbies of up to 8, though I’m not sure how performant or balanced that is. Have fun!
