You've seen the movies, you know what to do. The carbon version runs quite well except I haven't rewritten the sound routines yet, so that one has still not been released. To get to the download pages, please click on the appropriate monster near the bottom of the page. Here is the description of battalion from the Silicon Graphics homepage in Japan. Battalion wa 'kaiju ga bakuhatsu, hakai' wo kuri-kaesu game desu.
Battalion is a game where 'A monster blows up, destroys' repeats.
You can get it from here . The older version which works on the older non-G3 Power Macs is available here . I have also got battalion running quite nicely under OS-X but no audio yet. I got to be an extra in Godzilla X Megaguiras which will be out in Japan this December. More here .
