Played through the whole dlc, so I'm here to tell my feelings about it

The dlc took around 4-5 hours to complete, which is typical, I did a minimum of exploration and side quest, mostly sticking to the main quest. The atmosphere is very unique, you are constantly surrounded by danger, either be it by lobotomized humans, robo-scorpions, combat robots, nightstalkers, so on. OWB offers a relatively challenging experience, although not too hard to be frustrating. The storyline is good, basing itself on the theme of crazy scientist and experiments.

In the end, OWB is a very good dlc worth more than a look
