BF2 Buggy (gun doesn't work)

The last reply from Erghize on his Deviantart render of the BF2 buggy was in 2007. The Steam account I assume is his has been offline for 603 days. So, therefore, I assume he's dead. BTW: The gun derps up and down and doesn't have any way of telling when it will and will not shoot. MOUSE2 seems to fire at any time, but you have to have 1337 skills to be able to aim it. Will try fixing in later updates.

Place "hl2" in STEAMDIRECTORY/steamapps/YOURSTEAMID/half-life 2
