//
// Revision 1.27  2002/07/01 21:17:13  Flayra
// - Removed outdated adrenaline concept, made ROF generic for primal scream
//
// Revision 1.26  2002/06/25 17:41:13  Flayra
// - Reworking for correct player animations and new enable/disable state
//
// Revision 1.25  2002/06/10 19:50:37  Flayra
// - First-pass at level 1 animated view model (different anims when running and walking)
//
// Revision 1.24  2002/06/03 16:29:53  Flayra
// - Added resupply (from arsenal), better animation support (for both view model and player model)
//
