1 year after Steam Early Access release... there's still nothing to do. Game used to have big empty and boring world, where you traveled to objectives. Now it has 5 minutes playtime limit and before that you must return to your bunker or you will die. So big map was changed to small area around your bunker. Every 5 minutes you go out of the bunker, loot the same crates that got loot respawned and shoot endlessly coming few types of enemies.
That's all.
