Imagine, if you will, that you're a Space Invader. You'd be getting on a bit now, close to retirement probably. There might be the occasional interview or night club appearance as the retro tide once again washes in. Generally speaking, though, it's a quiet life. Only, hang on... what's this? Space Invaders EXTREME!! You're back on the frontline and once again employing the devious tactic of marching slowly from side to side, before taking one step down. It didn't work last time but it's sound military theory that just needs to carried out correctly. Over the top, chaps!

And then you discover that the pointy little bastard down the bottom now has a four-barrelled gatling gun and a gigantic laser that wipes out Binky, Chalky and Badger with one blast. Bugger.
