// $Log: AvHAlienTurret.cpp,v $
// Revision 1.8 2002/11/22 21:28:15 Flayra
// - mp_consistency changes
//
// Revision 1.7 2002/10/24 21:20:49 Flayra
// - Alien turrets now credit their owner with kills
//
// Revision 1.6 2002/09/23 22:08:14 Flayra
// - Removed damage upgrades for alien turrets (used to be needed for offensive upgrades)
//
// Revision 1.5 2002/07/24 18:45:40 Flayra
// - Linux and scripting changes
//
// Revision 1.4 2002/07/23 16:57:05 Flayra
// - Alien turret refactoring and fixing (the view offset in spawn() was causing them to always miss crouched players)
//
// Revision 1.3 2002/07/01 21:14:21 Flayra
// - Added auto-building, added damage upgrade (from primal scream), added vertical FOV (doesn't work yet)
//
// Revision 1.2 2002/06/03 16:24:08 Flayra
// - Moved chamber firing into an event, added turret constants
//
// Revision 1.1 2002/05/28 17:12:17 Flayra
// - Offensive chamber that shoots spit
//
