Soul Chip



20XX has an unlock system, where each run will find special enemies that are tinted black and blue (as opposed to their original colors). When defeated, these enemies drop Soul Chips. These are the only currencies that can be brought out to The Ark for spending. All other currencies will be forfeited if players end their run (whether through death or otherwise).

Soul Chips unlock additional Augments for players to discover through their future runs. They will also be gifted the Augment once, which lasts for the entirety of the next run. This usually costs upwards of 10 Soul Chips.

Otherwise, Soul Chips can be used to purchase Augments that players have already unlocked for a (usually) lower price, which lasts for the entirety of the next run. It is recommended to only buy these if players have any leftover Soul Chips after purchasing the unlocks, or the unlocks do not fit one's playstyle.

A typical full run should net 40-50 Soul Chips, depending on luck. The difficulty modifier Endless Mode is a great way to farm Soul Chips. Once players gain enough traction through sufficient upgrades (and ideally with a full set of Dracopent Core Augments), they can blow through levels very quickly. Going above level 20+ should net at least 200 Soul Chips.
