Galaxian (you could always spot the uncool kids in the playground, because they'd call it Galaxians) was in fact another fairly thinly-disguised Space Invaders variant, but it upped the style quotient by about a million percent. No longer did boring old white aliens trudge towards you in slow, orderly lines like a load of OAPs in the Tesco's checkout - these brightly-coloured sons of space bitches came hurtling right at the whites of your eyes in swooping, aerobatic attacks, all the while accompanied by a throbbing, unnerving electronic siren wail that sounded like a squadron of Stuka divebombers in formation three inches above your head. And what's more, you didn't even have the Space Invaders bunkers to hide behind - it was just you and your feeble single-beam laser against the endless bug-eyed hordes. At the time, gamers had never seen anything this intense.
