Forbidden Ingress is a first-person shooter in which you will fight with numerous demons, shoot hordes of monsters leaving the portals, build fortifications and do much, much more. Game events take place in our time. Scientists conducted experiments and experiments for a long time, and as a result were able to open the portal to where it would not be worth opening it. It was an otherworldly dimension inhabited by demons and previously unseen monsters. The portal was closed, but after some time, the portals began to open everywhere.
