wait 3.47;

for (i = 1 ; i >= 0.099999; i -= 0.175)

{

setDvar("sv_cheats", 1);

setDvar("timescale", i);

wait 0.00001;

}

wait 0.20;

for (i = 0.09999 ; i <= 1; i += 0.10)

setDvar("timescale", 1);

intoSlowMoTime = camTime;

if ( intoSlowMoTime > 1.0 )

{

intoSlowMoTime = 1.0;

wait( camTime - 1.0 );

}

//thread doSlowMo(1.0, 0.25, intoSlowMoTime); //setSlowMotion( 1.0, 0.25, intoSlowMoTime ); // start timescale, end timescale, lerp duration

//wait( intoSlowMoTime + 1 );

//thread doSlowMo(0.25, 1, 1); //setSlowMotion( 0.25, 1, 1.0 );

level.doingFinalKillcamFx = undefined;

pls help need it fast
