A Personal Combat Sim (or PCS) provides a permanent upgrade to a soldier's performance, but a soldier can only utilize a single PCS at a time; a soldier can overwrite their selected PCS at any time with a different or higher-grade PCS but the previous PCS will be lost.
PCS can only be installed once the Guerrilla Tactics School facility is constructed.
Each Personal Combat Sim comes in three qualities: Basic, Advanced and Superior, with the Advanced and Superior versions providing enhanced effects. All PCSs can be strengthened further by buying the Integrated Warfare enhancement from the Guerrilla Tactics School (augmented values in brackets).
Below are the known types of Personal Combat Sims:
|Personal Combat Sim||Icon||Effect||Basic||Advanced||Superior|
|PCS: Speed||+ Mobility||1 (2)||2 (3)||3 (4)|
|PCS: Conditioning||+ Hit Points||1 (2)||2 (3)||3 (4)|
|PCS: Focus||+ Will||10-15 (13-20)||15-20 (20-27)||20-25 (27-33)|
|PCS: Agility||+ Dodge||10-15 (13-20)||15-20 (20-27)||20-25 (27-33)|
|PCS: Perception||+ Aim||4-6 (5-8)||7-10 (9-13)||12-16 (16-21)|
- Spare Sims can be sold at the Black Market, they will even show interest in them from time to time. This is an odd occurrence because the store info page of PCS Chips clearly states that the people working for the black market have little use for them though it is possible they are purchasing them to resell.
- Upon a soldier's promotion, the Will bonus from a Focus sim is applied before the game checks if the cap of 100 has been reached, and if it has, that soldier gains no increase to Will. Therefore, using a Focus sim before max rank can be detrimental. For example, a +20 Focus sim is applied to a low-level soldier, which eventually reaches maximum rank and very likely has Will capped at 100. At that point, swapping the Focus sim for a different type (such as Perception) leaves that soldier with 80 Will.
- (Xbox One) Integrated Warfare does work retroactively, boosting a PCS that has already been applied to a soldier. Needs confirmation for other systems.
- There was a bug where soldier's stats could be raised by repeatedly swapping sims; it worked on Aim, Will and Dodge with the last sim the soldier used boosting the relevant stat by 1 when swapped. This issue was fixed with the game's 4th Patch.
