Unreal Engine 4
Single-Player FPS. Stealth game with advanced combat AIs. Sole full time programmer working with 5 Level Designers and 2
Gameplay designers. Target platform is Steam. Main AI, Gameplay, Engine and Programmer, AI Designer.
• Refactored AI early prototype made by a designer.
• Extensive use of AI Perception, EQS and Behaviour Trees.
• Customizable and context dependent Perception Strengths for each AI character and target. Player Skeletal Mesh bones are
also used for a very detailed Sight detection. AI Teams and Attitudes are managed by the Perception system. 4 different AI
teams up to date.
• Designed and implemented a dynamic Detection Percentage system that can grow depending on noise and sight stimuli.
Different states, animations, etc. can be triggered setting thresholds.
• Designed and Implemented a dynamic "Light Exposure" system, to modify the AI Perception Strength of the player. Several
skeletal bones are used for this exposure calculation.
• Implemented a dynamic "AI difficulty" system based on a single continuous value that can increase or decrease (as a result of the AI current state) inside a fixed range, which in turn will modify a set of values from the AI or trigger actions at key points.
• Started the Design a Squad manager for a group AI decision making and communications for player feedback.
• Started the Design of an advanced Squad/Combat decision system, using "Utility" and GOAP-like theories.
• Started the Design of Smart Objects system to be used by AI.
• Extensive use and customization of tools to debug AI and Gameplay: Gameplay Debugger, Visual Logger, custom
commands, etc. as main AI debugging tools.
• Writing of technical documents as well as participating in the design ones.

Unannounced Console FPS http://www.drstudios.co.uk
Unreal Engine 4
Multiplayer FPS. 4 players cooperative game against AI. Target platforms are PS4 and Xbox One with a possible port to Windows. Free to play. Team of around 25 developers with 6 of them programmers.
• Helped Lead programmer to refactor and fix structural and online issues. Assisted the team with Unreal Engine.
• Main AI Developer. Performance monitoring and reverse engineering of 1 to 2 years of AI code and blueprints
- Fix of performance issues. Refactored AI Controllers and created new behaviour trees and nodes.
- Made a Squad manager that controls tens of AIs and makes them march in formation. The agents are as simple as
possible to allow the maximum amount of them, the Squad Manager decides for them and populates its orders to the squad.
- These changes allow an Increase of the number of simultaneous combat AIs from 15 to potentially more than 200.
- Assisted QA developing tools to debug AI and Gameplay: A customised Gameplay Debugger, a complete Visual
Logger, custom commands, etc.
- Assisted the Code and Design team about AI and combat behaviours, wrote technical documents as well as participated in the design Wiki.
