Name:  ER Large Laser (Prototype)
Type (Category):  Weapon (Energy)
Reference:  Interstellar Operations (p. 103)

Description:
The discovery of the famous Helm Memory Core (also known as the Gray Death Memory Core) in 3028 sparked a resurgence of research and development in Star League-era technologies that had been lost since the early Succession Wars. By the time of the War of 3039, many of these technologies had re-entered limited production, though many still lacked the refinements of their final Star League-era specifications.

Advanced laser technologies were among the first to be mastered by the combatants involved in the War of 3039, but testing was still underway even during that conflict. The AFFS and LCAF both deployed experimental versions of the ER Large Laser (ER-LL-P) before then, but both armies would be surprised to learn that their Combine enemies had already managed to field their own fully-developed version before the first shots of the war were fired. (This historical note is hotly debated, even today, as many suspect the Combine-made lasers were actually provided by ComStar via a secret deal with then-Kanrei Theodore Kurita.)

Game Rules:
The recovered prototype ER large laser functions as its production-grade Inner Sphere counterpart, except that it suffers a +1 to-hit modifier to attack, and generates an additional 1D6 heat when fired.

This random heat generated is rolled each time the weapon is fired, and applies in addition to the heat the weapon normally generates.
