Tyr is a StarCraft AI, written by Simon Prins, a student of Utrecht University, Netherlands. It is a Terran bot, capable of mixed Marine and mech play. As of June 2015 it also incorporates Battlecruisers.
- Sacrifices large numbers of marines; despite relying on Barracks units to do large parts of the fighting, it uses no Medics.
Focuses on the use or marines, which are sent out in large groups without medic support to attack the enemy. In the mid-game, siege tanks are added, in the late game also battlecruisers.
