Red - Blinky: Oikake - "Akabei" (oikake-ru = to run down/to pursue/to chase down). Or of course the english "Shadow".. the guy is literally on your tail and can be thought of as your shadow

Pink - Pinky: Machibuse (machibuse = performing an ambush). Or in the english "speedy". He is indeed just as fast as Blinky and works with him to ambush and cut you off.

Blue - Inky: Kimagure - "Aosuke" (kimagure = fickle/moody/uneven temper). Or in english "Bashful". He is unpredictable. Sometimes he follows you, sometimes he goes away from you.

Orange - Clyde: Otoboke - "Guzuta" (Otoboke = Pretending Ignorance). The nick "Guzuta" means someone who lags behind). Or of course "pokey" in english. The guy is slow. He's always going somewhere on his own. But he does sometimes successfully cut you off, but almost never outright chases you.

Mislim da tih godina Half-Life nije ni imao dostojnu konkurenciju.... jednostavno igra koja je isla ispred svog vremena
