《戰慄深隧：流亡》（Metro Exodus）將有光線追踪和四季交替，最近，4A Games又介紹了關於晝夜系統的新情報，遊戲中晝夜變換會影響NPC的行為，同時也會催生更多對付敵人的戰術。
創意總監 John Block 解釋說，人類 NPC 的行為會更貼近現實生活，白天外出巡邏，晚上回到營地休息，可能在篝火旁打發時間。在某些情況下，白天攻擊敵人面對的阻力較小，因為會有巡邏的警衛來幫助玩家。而晚上由於 NPC 都聚集在營地裡，玩家可以依靠黑暗的掩護四處走動探索。
In some situations, he said, that means hitting the base during the day will mean facing less resistance, since you’ll have some guards away on patrol.“Or, at night, they’re clustered around their campfires and sleeping and all of them are in there, but you have the cover of darkness to sneak around,” he said.Naturally, night is when Metro Exodus’ scarier beasties come out to play, so that will have to be taken into consideration as well. Players can rest to pass time, too, so it’ll be possible to try one approach a couple times, and then wait until evening or morning if it’s not working out.
《戰慄深隧：流亡》將於2019年2月22日登陸 PC /PS4 / Xbox One 平臺。
