Metro Exodus is the 3rd game in the Metro series. It takes a departure from the strictly linear design of the 2 previous games and introduces open-world elements.
-The elephant in the room: it's not an open world game. It's not a Ubisoft game with a huge "go anywhere, do whatever" map with endlesly copy-pasted side qeusts dotted all over it. Instead, it's a series of of open maps - some are small, some are large, some are linear like the classic Metro and some are open just as much as they're linear (akin to the level design in the original Crysis) - and each map has a clear end goal, with the open world serving as the freedom of approuch to tasks at hand and to achieve side goals/missions that relate, often dirrectly, to either the main task at hand or the plot. The other big concern here is the departure from the clastrophobic tunnel of the Metro, for which the game is named, but without going into spoilers- you'll spend enough time in clastrophobic eviorments both on and below ground.
In my opinion, the open-world was handled tactfully
-Atmosphere: what always sets Metro apart is the atmosphere. Here, it's as briliant as always.
-Gameplay: in terms of gameplay, it's Metro Last Light V2.0; Movment is smoother, shooting is more reactive, enemies are a bit smarter. That's really it.
-Mechanics: an understadable change that I didn't like was replacing bullet currency with 2 types of crafting materials (bio and tech). It allows you to clean your gun (that will jam otherwise), make bullets (you'll still always be short on those) and other small stuff.
-Story: I think it's good and less formulaic than others. There's no grand end goal (some time is spent on looking for a goal at all) and no main villain. It's about the journey and the people.
Note: when playing, note that not all enemies are assholes that deserve to die. Saying byond that is a spoiler.
Note: I bought on a different store before reealizing it's aavlible on GOG.
