Knowledge of machine learning is becoming more essential in many fields. This thesis explores and outlines the basics of machine learning through the complex game StarCraft II with limited prior knowledge and resources. In particular deep Q-learning in combination with imitation learning was explored in order to reduce the time required for an agent to become capable of playing the game. A few simpler environments were used as initial challenges before StarCraft II was explored. For all environments, the thesis reports a comparison of performance between the agents utilizing imitation learning and those that did not. In the cases of the simpler environments, agents using deep Q-learning combined with imitation learning showed significantly improved training time. Due to problems with the reward structure for the complex game StarCraft II no conclusion could be drawn about the implications of imitation learning in complex environments.
