Nice way to "git gud" in the game is to build up your skylab as much as you can, and send Promethium to your ship to sell. No need to pay for this game at all. You can literally farm Uridium in game from killing enemies. Sure it takes along time, but it's still better than paying.
Best way to get kills. Press "G" and go running around outside of your car gunning everyone else down with your infinite ammo machine gun. Only the bots can kill you once your outside your car, or so it seems. You can die by being ran over, but that's usual.
jooe15 the negative/vamped creature does do damage. Your looking at the wrong health bar. Try looking at your own. It works like that as a negative attack monster will heal what ever play its targeted at. A vamped creature steals health, and so a negative attack monster that heals the opponent while being vamped would damage yourself. Singularity decks are hard to use sometimes because of that alone.
