However the record seems to be temporary as it is made in a childish way, with a falsetto/Muppet-like voice.
The sound file "tattle1.wav" located in the sound folder for the Alien Assassin in the playable Half-Life 2 Beta files indicates the Assassin was at some point to taunt the player. Similar to a Stun Baton sound, it was likely related to the Assassin's Hopwire Grenades. A related sound file, "ball_zap1.wav", can still be found in the Half-Life 2 files, in the folder "/sound/npc/assassin/". This suggests they were to be related in some way. They have an identical orange sphere on the back of one hand, looking like some sort of lid (the right hand for the Alien Assassin, in lower resolution, the left for the Cremator), similar arms and hands (except that the Cremator has only four fingers), and also lines on the hands (although the Cremator has them on its gloves instead of the skin like Alien Assassin). Both the Alien Assassin and the Cremator bear some similarities. When shot at, it sounds like it is metal. The blending between the limbs and chest/waist texture files are also not well finished. The hands and feet have turned a bright red, and the bones of the forearms have become visible. It appears as even more transformed than the Standard Zombie, the Headcrab's rear left leg going inside the Assassin's back even further than in Standard Zombies, to reappear near the Assassin's right shoulder. It was also to have a Zombie version (also known as the Zombie Assassin), but it was never completed. It was also to fire smoke to conceal its movements, throw Hopwire Grenade', MK3A2 Grenades and knives stored on its back, and quickly pounce the player.
Like the Combine Assassin, it is likely that it was to be a quick and resourceful enemy, moving swiftly and performing flips, rolls, and other movements. The Alien Assassin has long claws used for slashing targets, red spikes on the top of its head, a breathing mask and pipes in its eye orbits, and apparently only two toes.
