I’ll give a couple of tips after watching brim get schrecked on stream:

• This is not a fair fight, the blue guys are wearing armor and Mokoto isn’t. Do not just engage without getting the drop on them.
• Headshots have a 3x damage multiplier but are not instant-kills unless you hit in the back of the head at very close range.
• The X20 is an exception, it does so much damage that it can instant kill with a headshot even at longer range.
• Like in Counter Strike, any amount of movement adds random spread to your shots. You have to stop moving to be accurate.
• Crouching alone does not make you silent, you have to also hold the sneak key.
• Mokoto is immune to headshots but unlike the Grunts in Ctesiphon, the bad guys are not wearing helmets
• You can do a silent takedown by interacting with an enemy’s back. This will work even if the enemy is already alert but you need to have lost them for a few seconds so they don’t just track you.
