Nintendo's Super Smash Bros. Melee fighting game can be emulated on modern hardware allowing us to inspect internal memory states, such as character positions. We created an AI that avoids being hit by training using these internal memory states and outputting controller button presses. After training on a month's worth of Melee matches, our best agent learned to avoid the toughest AI built into the game for a full minute 74.6 of the time.
The work most relevant to this project is that of @cite_5 , which applies Reinforcement Learning to create an agent for Melee. Utilizing an actor-critic model with a deep architecture and self-play, they were able to achieve excellent results with the Captain Falcon character on the Battlefield stage, going on to even beat a number of professional players. Their agent is however known to have difficulties dealing with unusual opponent behavior that has not been seen in training, such as the opponent simply crouching.

In this paper, we propose a novel framework for training vision-based agent for First-Person Shooter (FPS) Game, in particular Doom. Our framework combines the state-of-the-art reinforcement learning approach (Asynchronous Advantage Actor-Critic (A3C) model) with curriculum learning. Our model is simple in design and only uses game states from the AI side, rather than using opponents' information. On a known map, our agent won 10 out of the 11 attended games and the champion of Track1 in ViZDoom AI Competition 2016 by a large margin, 35 higher score than the second place.
