Sup Geez, you guys have these hatches all around the Livonia airport. It woud be nice if you make a tunnel system. For example, this one is located south from airport (between airport and Gliniska, in the tree line), you could make a single tunnel that leads from the hatch to the airfield headqurters, or just to the similar hatch on the arirfields territory. Yes, it will be quite long tunnel (200-300m), but nothing fancy is required, you can make 3d model of a tunnel like 15-20m long, and just keep duplicating it. Just a few small rooms inside, or no rooms at all, throw some proxies of boxes, garbage, lockers or something like that. At the entrance and exit place a ladder (like sewers entrance), and for the hatches use door mechanic, but with slide instead of opening. Yes, it will require a terrain editing (like with Dambog), I haven't tried it yet, but I'm sure it doesn't take a lot of time and efforts. All that will add some unique vibe to the game (airfield + toxic + tunnel). It would be nice to see more undergrounds in the future, not as big as Dambog ofc, small ones will be nice (a bunker or a mine, ony one more will be more than enough), plus add a few of these underground passages and you'll have underground Livonia. You can add Hanna story to it, or the story of Livonia itself (I mean zombie apocalypse). I believe in such a big country (or province) there should be more than one underground military, classified medical, or industrial places. Have a nice day.
