The Titan Optical Maser Array was the Titan version of the Optical Maser Array. It was extremely destructive when used strategically and was almost as strong as the RYNO. Like the non-upgraded Optical Maser Array and Laser Tracer, it created a small force field that protected you from enemy fire.
Description from game
"Using stimulated emission to highly excited captured hydrogen compounds, the Optical Maser Array forces the resultant amplifying medium into a resonant cavity, capturing the feedback that is created and producing a coherent radiation beam of unimaginable power."
