Heat: Tunnel Vision Expansion

Heat: Tunnel Vision Expansion introduces sophisticated environmental challenges through two meticulously designed racing circuits. The Spanish Grand Prix implementation features subterranean passage mechanics requiring strategic decision-making under reduced visibility conditions, while the Netherlands configuration balances high-velocity straightaways with technically demanding directional transitions. The expansion integrates historical authenticity through 1965 Championship season parameters and introduces aerodynamic modification options via Front Wing upgrade cards that facilitate strategic drafting mechanics. Technical course elements including chicanes and tunnels increase tactical complexity, while expanded event cards introduce additional situational variables. The comprehensive component array includes a reversible circuit board, vehicle representation with corresponding gear indicator, player interface panel, multiple card categories (base, Heat, Stress, Upgrade, Sponsorship, Event), and documentation materials. This implementation supports expanded player configurations to seven participants (eight with Heavy Rain expansion integration), enhancing both mechanical depth and competitive variability.
