This patch is made for the 2001 and 2001-2002 mappacks. The fixes are as follows

-Removal of zombie sounds from the script(they were from may 2002
shotgun cocking and reloading sounds replaced with hl1 sounds(as the original sounds were from 2003

-uses e3 2003 shotgun sounds(they were actually from october 2000)

Pistol uses hl1 sound as the original sound was from 2003( we are unsure what whas used before 2003 so this makes scence)

Sentences.txt changed to play correct combine soldier sounds(which turned out to be from november 2000)


Ar2 model to be as close to the original 2001 ar2 as possible
(fixed model by quakercraft)

-uses 2001 ar2 recreations by Cremator

Explosions use hl1 sounds instead of 2003 sounds( we are unsure what whas used before 2003 so this makes scence)
