Gameplay Changes Between etmain and ETPro
Players may now open doors silently by crouching and pressing +activate.
Players may notice when they are wounded and waiting for medic, that freelook is no longer lagged. Also, the wounded freelook camera should no longer 'lock on' to non-medics.
Players will hear "prepare to fight" when the warmup countdown begins, and "fight!" when the round starts. Players may disable this with the cvar cg_announcer.
When a player gets a knife kill, both the attacker and the victim hear the 'OSP goat' sound. Players may disable this with the cvar b_goatsound. (Sounds used from OSP with permission)
For weapons without an alternate fire mode (non-silenced pistol, sten, thompson/mp40, etc) players may use the weapalt<tt> button to reload.
