since i can't edit the above post, i'd like to add that i've blasted through the first 23 levels (+3 bosses) of Centipede: Infestation. It's ironically tedious and fun at the same time.
now that i've gotten better, i need to go back to some earlier levels to replace the silver medal with a gold one. i think you can't get hit more than twice. you have 9 hit points per round. gold medals unlock different characters and outfits for your characters. seems like the main guy and girl have 4 outfits each, then there's other silhouettes of people i haven't gotten to yet. one of them looks like... nevermind that's probably a spoiler.
one thing i'd like to mention is the dialogue is hard to hear. you can crank up the voices in the options menu as well as turn on subtitles. the story gets really cheesy at times, and there are references to other Atari games. so far i've heard about Missile Command and Warlords. LOL.
there are a total of 17 different achievements in the game; 5 of them pertain to gold medals, 5 of them pertain to racking up a score, 1 is for clearing the game, and the rest are for various tasks such as not upgrading your gun for an entire level.
i have 11/17 of them at level 24.
there are at least 40 levels. i'm going to guess 40 actual levels and 5 boss levels. i'm not sure yet but it seems that way.
ok, break's over, it's time for another few levels to run through!
