The heart of Impact Winter is the Event System which adapts to the decisions or choices you make, no missions. The game has a beginning and an end. No two games are the same due to dynamic 'Story Events' that replace the traditional 'mission' structure. These events can be completely random (wandering strangers'; kidnappings; Ako-Light malfunctions; strange illnesses) to scripted scenarios that are tied to certain conditions (storms damaging the Church; frostbite from over-exposure to the cold, getting lost in a 'Whiteout'; depressed team members going AWOL). Story Events are designed to test your leadership skills - and because of their random, unpredictable nature - they will often require plans to be altered and actions to be prioritized. Everybody's path to survival will be fraught with different challenges.
