Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.

Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Metal Gear Solid 4: Guns of the Patriots
battlefield factions act on scripts
The Suffering

The Suffering
