There's a new update for Operation Extirpate, here's a list of everything thats new:

-Added 'Options' to the menu

-Added 'OK' buttons to windows such as Help, Credits, etc.

-Added HUD

-Added new detection system:

a. Shows player how aware the closest enemy is of him.

b. Takes gunshots, distance from player and grenades into account

-Added execution system:

a. Players can sneak up to enemies facing away from them and enter a phrase into a dialog box. That phrase is then said by the player to the enemy just before you are able to quickly shoot him in the head for an instant kill.

-Helmets that are shot off can now be shot while in the air

-Pressing 'G' now switches between American grenades, and German

-You can now shoot grenades, first shot propels the grenade, the second triggers the explosion.

-Each gun's bullets now vary in distance it travels, so pistols will now travel as far as rifles, etc.

-Cursor image shows whether the bullets of the gun can reach where the mouse is pointed.

-Dead bodies can now be shot, bullet holes do not appear but you can see the body move from the bullets.

-A shotgun was added to the list of weapons that will be created (Winchester Model 1897).
