Thanks for the tips! :) There was still some ammunition wastage anyway (the dogs behind the restaurant and the zombies at the exploding barrel), but the game’s hitbox system is so full random that I’d rather let it go and leave it as it is. It can be very annoying when I start very well and then such small mistakes come in. It’s unpredictable how your opponents will move and so it will give you time differently, no matter how much I shot from the same position. This was especially frustrating with the exploding barrels when all the zombies explode, but only gives 72 seconds instead of 82. And that's when i can start over. And The Mercenaries has many such points. I might have had the S rank, but honestly, my goal was the A rank and to take the time above 10 minutes. I'm happy with that too. But I'm glad you did and congratulations! :)
