MGSPW Ex Op 4 S Rank 0:41

The time on the results screen only counts from the beep when you enter the first shooting zone. Mine placement is free. S Rank score threshold is 10100 points, explosion hits give 200 points, and headshots give 500. With 6 mines, the maximum that can be placed at a time, there is no room for error. Some day I'll grind for 40 seconds but this level has become unfun due to the setup. Side note, it's possible to get hits with the projectiles that claymores shoot out, meaning mine headshots are technically possible. This only seems to work on the targets that aren't already spawned at the start though. S Rank Speedrun of Metal Gear Solid: Peace Walker Extra Op 4: Time Attack on PS3
