GTFO is a stealthy survival game. You cannot just run through to complete it. There are monsters on every corner that you have to kill and get through.
GTFO is best with friends and other players so that you can run through and take out the enemies quicker. But you also get bots now which is nice.
You are going to have to move stealthy so you do not disturb the creatures unless you are prepared to get horded and surrounded quickly.
You are going around opening doors, collecting artifact pieces trying to complete the waves. They get harder and harder trying to complete since you have to find terminals hack into them find the door your looking for if it is even near the area and then you have to keep going and unlock doors and so much more all while trying to survive.
This game is a great rage inducer just trying to make it through.
Each play through is different. The map changes and nothing will be in the same place which makes the game even harder to get through.
Just a heads up, this is a dark game so you are going around with a little bit of light from lights on the map and flashlights and it makes it hard to see. This makes the game more intense and eerie because you can easily stumble upon a creature that is sleeping in the dark just waiting on you to get there so it can have something to eat.
