Playing Neo Scavenger (which came with the recent Humble Bundle). It is a rouge like game where you start by assigning a limited number of character traits and skills from a wide range of available skills (e.g. melee, strong, electrical, mechanic, medic .. etc.) and then the game begins.
Your characters wakes up in a cryo-chamber where the world has changed. You start with nothing and has to scavenge surroundings (woods, buildings, sheds, cars .. etc) to find clothes (you start with patient garment), shelter, food, water, heating, medicene, weapons and so on. You have crafting as well.
It is very realistic and the scavenging part is done to high detail, for example you can't just 'pick up' water from lakes, you have to find a bottle first and then put the water in. YOu will need to keep warm with clothes and otherwise (i.e. crafting fire) to avoid hypothermia.
It is turn-based: so your movement and actions over a hex grid each take a single turn. At night, the grid is not visible (unless you have night vision googles). Combat is also turn-based as there will be many "BadMatha" that will try to kill and loot you, but you can defend yourself in many ways (using ranged and melee weapons). You can also reason with npc as you have the option.
The atmosphere is well done; grim, raining sometimes, there is strong urge for survival as all conditions are againsts you, and you feel very happy once you find a plastic bag to put your loot in, or new pair of trousers, or some clean cloths for your wounds!
Well thought of and very detailed scavenging/rpg game, and addictive.
Downsides, 2 for me:
1) its a flash game
2) the user interface need refinement and it takes some perma-deaths to get used it.
An indie gem, and highly recommended (you can grab it now from the humble bundle as pay what you want).
