The Metro series delivers a very focused experience based on survival and narrative. You'll be attempting to make your way through tight, deadly environments in order to make it towards any objectives you're sent on. This is particularly present in the first two titles, 2033 and Last Light which were bundled in a remastered Redux bundle. This is then followed up by Exodus which presents a more open world type of situation. The survival elements are always present as you conserve ammo, craft and try to make it out alive. There's an element of choice in the franchise, not only in the story but also in how you tackle scenarios that are presented to you.
