As a fan of Stalker I had to try this out, and I'm impressed by the effort shown in Tunguska: The Visitation. The atmosphere is outstanding, love the music and sound design. The dialogue options seem meaningful, with incentive to talk to all the NPCs and hear everything they have to say to get the full story. The environment can be deadly, but the same things that make it deadly can offer tactical options in tough combat situations. Well made game with satisfying challenges to overcome, and developed by a one-man studio. Very cool!
