6. Research Bluescreen Rounds To Destroy Robotic Enemies
Enemies have a tendency of upgrading themselves as the game goes on, becoming stronger and more durable with each new encounter. Robotic enemies in particular can become a nightmare in the latter half of the campaign, but there's a way to counteract this problem: research Bluescreen rounds. Doing so will grant you +5 extra damage per shot, per enemy, turning robotic enemies in particular into a minor annoyance, instead of devastating obstacle. If you equip a sharpshooter with the rounds, you'll even be able to take down some of the more powerful robotic enemies, like the Sectopod, with just a few well timed pistol shots. It's OP, but damn is it effective.
