From B-Ball, quite a useful-looking arena remix, with its own special gimmick. Why it is "Fith" rather than "Fifth" I don't know, as the gimmick involves the fifth time you shoot one particular white rectangle on the wall. Not that anyone sensible is going to shoot it five times, as each time you do, the whole nuclear reactor shakes and shudders, almost throwing you off your chair. After the fifth time, expect to see a small mushroom cloud emerging from the top of your monitor! Don't say I didn't warn you... Well, actually, a trapdoor opens then, allowing you to jump down to a lower "sewer" style level. Don't worry, there is an elevator to bring you back up.
The original "BETA" version had one particular wall, just near the megapower, strobing and flashing and generally making a nuisance of itself. But the newer version behaves itself nicely - though now that I have explained to B-Ball how to get into that "sewer" level (!), he is planning to make a "final" version as well. But as it stands, two to four players can have a speedy and enjoyable game here.
