The games actually about 15 hours long because weve got so much to do with the narrative and all the different mechanics of the alien. On top of that we have the other threats about the station, we have a big long story that folds out. Also its a bit like a Metroidvania game where you have a linear story you go through but you can also go back and explore areas youve been to. You can go back to areas and find new things, explore and open up new areas. Theres a lot to do in the world.
The difficult thing is nailing a time because people can play for absolutely ages without even seeing the alien because theyre being really careful and really stealthy, theyve done nothing to call him down or there have been no explosions that he has come to investigate. Those people can get through it fairly quickly.
