Supernova works for me on this game. Disappointed about the art work though. The original art work in the first game was so much better. The bullet proof vest, for instance, looks like it was done in MS paint.
This game still resonates with me more than a decade later. The music, the symbolism, everything. Addiction, recovery, appreciation for the little things and living in the moment. Sometimes it's sad to be alone, but it's still good to be alive.
I think the alien campaign is really great because it's so hard. Especially on rocket race. Your teammates are absolute morons and have the worst weapon in game. So you have to kill 2 extremely hard guys while your guys keep dying and suiciding.
At most, 1 tank coin per level. You'd get around 40 by the time you're level 40. So it wouldn't be too much of a difference, but would still be nice if you wanted a new tank, map, or theme.
Change the medium to an easy, change the hard to a medium and make it level 5. Make the hard level 12. Then add an impossible badge for a certain amount of wins. Possibly 250+?
