So yeah, does anyone know how? I have gotten to level seven twice, once on Newgrounds website. Moved bases, passed checkpoints just like the game description says is required for the autosave. But, it is not saving for me.
whenever you have defeated another notoriety attackers, the game does an auto-save. If it doesn't, try increasing savefile space for armorgames.com, or try another browser... it did save for me.
You must not under attack. Stop your criminal activities until all invasions were hold off could work, but if you passed too many check points enemy waves would seem endless that you cannot really hope to save the game at that point.
Once ultimate weapon in progess the enemy attack won't stop, can't save there.
