Outcast

Oil
The voice files of Motazaar contain this removed conversation about oil and a special container, presumably the Oilcan, implying that at one point you could find a unique material exclusively in this region. The conversation is between Cutter and a Recreator, indicating this was most likely a crafting material.

Additionally, this clip of the Advisor Headset makes reference to petrol. Considering how the ADVISOR Headset detects materials, this presumably would have played when approaching one of the above mentioned pools of oil.

Collectors.sfx
Among the general voice files lies this mysterious clip. It seems to be a collection of voice acting outtakes and scraps of dialogue that are actually in the final game (Specifically the last three lines). Why it was put in the game's files, and why its name is 'Collectors', is a mystery.

Weapons Detected
There are many voice clips for weapons being detected by the Advisor Headset. As the Advisor only warns you of located items on the ground, this suggests you were at once point supposed to find weapons and upgrades lying around the regions of Adelpha, whereas in the final game you can only get them through merchants, rendering these clips unused. This is supported by an image released by one of the developers of the map editor. (boom_gun is the internal name of the LN-DUO 500)

Additionally, it implies the X-Ray function of the binoculars were originally an upgrade, whereas in the final game they come with X-Ray vision from the start.

Miscellaneous Advisor Clips
Another unused Advisor sound file. (There's a lot of these!) This one refers to an 'HK-P12 Ammo Clip', whereas the final game uses a different shorter file, simply calling it 'HK-P12 Ammo'.

The Advisor detecting a lifeform. Most likely unused as being told about any animal you might pass by would get annoying after a while.

The Advisor scanning Zorkins and determining their possible monetary use. Ingame, it only ever refers to Zorkins as metal.

The Advisor saying your inventory is updated. Again, most likely removed because it would get annoying, considering how often you are handed items.

Unused Cutter Clips


Two Cutter voice clips, vo_dragon_0 and vo_dragon_1. Dragon being the internal name for the Achondar suggests one of these would play when entering its arena, but in the final game Cutter is silent.
