New Features in Metro Exodus
Dynamic Weather and Day-Night Systems
Considering Metro 2033 and Last Light almost entirely took place underground, there was no need for any kind of day-night or weather systems. Making the change to an open world game in parts does require that, however.
These systems do much more than just change locations visually, they can actually affect gameplay and how you approach each situation. During the day, enemy groups will have more men out patrolling, meaning their numbers in the core base will be thinned out if you need to get into a firefight.
On the other hand, at night they’ll sit around campfires or sleep, making it easier to sneak in, however, mutants are more active at night so you’ll have that as an added danger.
Weather also affects your options for stealth and combat. For example, a thunderstorm will muffle the sounds of your footsteps and rain will reduce your range of vision.
Because of all this, you might need to change your strategy on the fly to account for whatever weather system might roll in.
