Well Han, keep your head up and take support from your family when things get rough. That sure saved my ass when things got rough for me.
As for Alien Syndrome, I never played this one in the 80s but I did play it in the AtariAge high score club 7-8 years ago, so I'm not totally green with it. Actually, I just checked; the score I got in that competition is significantly higher than what I've posted here. That's the problem with games like this - so much of it is memorization that if you go a long stretch without playing, you lose it all and have to almost start over.
In digging up the old AA thread, I was reminded of a play tip I posted back then that I had completely forgotten about, regarding how to handle the 2nd boss that throws those blobs at you. I was really struggling with that boss the other night because the blobs are very difficult to avoid. What you can do is grab the flame-thrower weapon (not the fireball weapon) and when the monster lobs the blobs at you, just stand still and let them land around you. When they land, mash the button and spin around in a circle. The flamethrower will nuke the blobs around you and give you a chance to attack the main monster.
