Howdy great peeps,

Here are clear instructions on how to spawn items,
since the developer explained it very, VERY poorly..

Instructions:
On the title (first) screen (not the loading one), type in: pixellore & then press Enter.
(It will go towards the menu selection screen whilst typing it, this is intended)

But be careful to type in ONLY pixellore, any wrong button in front or behind,
and the command will not work (requires restart), be very careful to type it in precisely.
(If you did it correctly, in the lower left of the screen you will see "Debug activated.")

Then load your save/start a new game, and press \
Left down on the screen, you can see what you type.

If you want, per example, a XL Backpack type in the following:
spawn item 328 1 (328 being the backpack ID and 1 being the amount)

(If the Journal or Map opens whilst you are typing in the command, it doesn't matter,
but some numbers may activate quick-use items, so be careful about equipped items)

If you want to spawn a new item, press \ again and remove the letters (backspace).
Item IDs are located in (and the file name is called "ItemDescription"):

C:\Steam\steamapps\common\Subterrain\Subterrain_Data\StreamingAssets\Localization\English

Kind regards & enjoy!
