PC users of the Fifa 18 demo can possibly extend the length of the half-time:
- Open the "Data" folder in your Fifa 18 folder
- open the "locale.ini"
- under the line "FIFA_DEMO = 1" insert the following lines:
[]
SKIP_BOOTFLOW=0
HALF_LENGTH=6
AI_SETTING_HALFLENGTH=6
//
Behind "HALF_LENGTH= and "AI_SETTING_HALFLENGTH=" you can enter 6, 10 or 45 minutes halftime. After this, save the "locale.ini". I do not know if this really works, I´m PS4 user.
Here the source for this in german:
