Armored Core 1 on PS1. The 1st two missions are "kill the protestors" missions.

The mission briefing describes the squatters as previous tenants not wanting the real estate typhoons to drive them out. And the Strikers mission is literally described as workers wanting better working conditions.

The mission description literally says they are citizens and the guard(their police) cant use force, and for you to teach them the rules of society. Conditions for missions success... killing them all...

You literally start as the bad guy of the series.

From Software wasn't playing around back then.
