Я так понемаю это строка в XP.inl
Код
// Check for a team kill
if ( get_user_team( iAttacker ) == get_user_team( iVictim ) )
{
// Remove XP since he killed his teammate
iBonusXP = XP_Give( iAttacker, -1 * iXP );
// This message should be displayed no matter what XP_kill_objectives is, b/c it's a no-no
if ( iBonusXP != 0 )
{
client_print( iAttacker, print_chat, "%s You have lost %d XP for killing a teammate", g_MODclient, -1 * iBonusXP );
}
}
