Saw in a review that missions have a 30 min timer, can someone who owns the game confirm this please?

So it has a 30 min timer but it does not end the mission. It just spawns a lot of the nightmare esk~ enemies.

A second timer will appear saying "5 mins till storm ends" then "30 mins till storm starts" so you have infinity time in a mission just that it gets difficult

Many thanks. I like the look of the game but I must admit the thought of a quest timer turns me off a touch

30 minutes is plenty of time to explore the area that you are in, craft and collect items, kill enemies, and complete the mission. That said, if you run out of time it doesn't really matter.
