What's the one game you can think of that you were never able to beat?
For me, it's probably
Xenon. It's a vertical scrolling shooter where you can switch between being a tank and a plane, the first game by the Bitmap Brothers. It's been haunting me since I was a boy and I loaded it up on an Atari emulator a few days ago.
My god, it's brutal. You get 3 lives to do the whole game with no saves. There are points in level 2 where, if you lose that first life, you are pretty much guaranteed to lose the other 2, because the level is practically impossible once you've lost all the weapon upgrades and gone back to the basic blaster. I got to level 3 once and it's merciless. Those little ground bastards ambush you from all sides ...
But it's a fantastic game and I love it. Especially the music, omg ...
Did anyone ever beat it? Seriously, if you want a challenge these days, go back to the '80s, lol
(P.S. Man, what is up with the url links in this forum?)
