Frost is a role playing game for PC and consoles, where you are trying to survive and protect your family from mythical beasts and nature itself. you start off by building a small hut for your family to live in, primitive at first but you can develop more to have a more comfortable life.
taking your bow and some arrows you say goodbye to your family and venture out into the snow to look for food. the game works like this, your family has certain needs that must be met such as hunger, warmth, thirst and so on.
so first of all you need to go out and find some food, you dont have an unlimited amount of arrows so you need to hunt and track animals such as deer and rabbits for starters, given the small amount of arrows you cant run around shooting everything, you need to make it count.
you can go out and get wood for fires aswell, so all in all its basically a management game, you wake up in the morning and check what is most important for your family at that moment so you would prepare and grab the stuff you would need to fulfill that need, such as taking an axe out to cut wood etc, you cant hold everything you own so you need to be smart about what you take.
sometimes you can stumble across ruins of old settlements that you can scavenge and maybe even find ideas for items you could use to improve your life.
there is also danger by going outside, mythical beasts roam about the countryside and are incredibly vicious and bloodthirsty, you must either hide from them or attack them, you cannot really do well with 3 arrows so you might want to wait till you have some traps and more advanced weapons, so you would have to plan instead of running through and attacking anything.
