Kind of odd how you call it a stealth game, when it doesn't really have any of the trappings / mechanics of one (ie Splinter Cell, Deus Ex Mankind Divided, Dishonored 2, etc). There isn't a dedicated stealth button, there isn't any way to effectively distract or lure targets to a specific point, you can't go prone, crawl, or perform slides. There are no crawlspaces, vents, or secret paths. You can't climb or platform or wall hug/shimmy. You can't do a silent takedown (lethal or otherwise), you have no infinite emergency attack (stab, slice, punch, kick, blaster pistol, gauntlet etc) and the only way to silently kill foes is with a silencer. You have no gear that improves stealthiness (quiet steps, camoflauge with environment, active camo, null signature, etc).
