I've finished Metro series (all on hardcore) and here's my take on it.
- Metro 2033 Redux
Guns are sluggish and unrefined, weapon and ammo placement is bad you never have enough currency to play around with mods. Play only if you're a fan or if you're interested in the story.
-Metro Exodus
Bit of a letdown. While technically impressive with the best exploration, environment and weapon system but it's undermined by horrible movement and boredom of combat. AI is absolutely brain dead and zombie enemies are fun in the desert and nowhere else.
