This study presents and substantiates a comprehensive methodology for the accelerated training of Middle-level Unity developers. The methodology is founded on a synthesis of andragogical principles, a constructivist approach, and Project-Based Learning (PBL). Its central element is the "Strategic Experience Augmentation" strategy, which is aimed at overcoming the "experience gap" that constitutes a key barrier to employment for novice specialists. This paper provides a detailed six-month curriculum (roadmap), a mentorship support toolkit including formalized code review and interview simulations, and metrics for evaluating the program's effectiveness. The methodology is positioned as a solution to the structural talent deficit within the game development industry, ensuring the preparation of specialists capable of delivering production value (time-to-value) in the shortest possible timeframe.
