Hi,
I think you have to hit him 10 times. I cann't be sure though.

Hmmmm, I'm sure he took more hits. I must play through that batle again at some point and count myself.

But to answer your question, Yes indeed Archer, there are two bonus levels, (or the same bonus level repeated twice).

I can't take any creddit for discovering them though, I found out their locations from Brian P's Superliam walkthrough. So, to Paraphrase Brian, on act two of both the suburban streets and Waterworks stages, when you get to the first sewer/drain, instead of pressing right arrow six times to jump it, just arrow three times and you'll be taken to the bonus level ----- which also handily skips out the rest of the act for you, as well as giving you several thousand point bonuses and extra lives.

Btw, Brian and whoever else found these must have had iether the devil's own luck, or a huge store of patience.

Well, usually they'd be leaked by companies to gaming mags and such to drumb up interest for the game, and sell the magazines of course.

My standard policy upon obtaining a new game always used to be to ring Nintendo Hotline Uk (when it was stil running), and get whatever cheats there were for the game. now of course, I just C&P from gamefaqs ----- or this site ---- lol.

Oooh, I'm surprised you can actually kill them, I thought they were immortal.

silver spaceship 2 was actually one of my favourite levels, partly because of the extra lives cheat, and partly because spaceships are just cool. Imho the hardest stages in the game are lava 2, water escape and lethal lab 2. Water works 2 was a litle tough but not as hard as those were.
