Jetpack Pegasusmod was interesting!
I remember the players: lelis(RU), lla(FR), bond(FR), TP555(GE), Captain Ezy(US),Emm@ Peel(SW) ...
Unfortunately, the "Contract JACK" server was VERY unstable, each player could crash the server if he typed a certain combination of special characters on the keyboard ... this error has not been resolved ... few people knew these codes .. :D
