OK, this is the last score I will ever post. I just got 210,602,550 (NTSC mode) and died on level 431. I had $463,000 when I died.
I don't think I have to explain how I died because it was exactly how I die every time - an alien popped up and gave me a shit weapon before I could avoid it. I went through the entire level with single shot and only had one bloody alien left (that I had already hit 10 times) and I just had to kill that one damn guy to go to the next level. One or two more hits and he'd be dead, but he shat out loads of bullets at the exact second I moved under him to shoot.
Unless somebody can post a higher score (come on Steve, find that paper from 1995!
) I'll just have to assume the title of "Champion of the Known Universe".
