Increase default squad size is a mod for XCOM 2, created by ArsenicTouch.

Description:

Default size is 4, which can be expanded to 6 with upgrades.

This tweak increases default size to 6, which will increase to 8 with the base upgrades.

(Based on xcom 1 long war numbers)

The UI only supports up to 6 on the screen.According to pcgamer, it would support 8 but that appears to be incorrect.

If you want more than the 6 + the 2 from upgrades, I can provide optional files.

When it's set to higher than 8 in game, you'll have 9 soldiers with you at your spawn point,

the rest of your soldiers will all appear on one square a little bit from your starting location.
