This FPS, gameplay-wise, is a good, nuanced fusion of old-school fluid movement with punishing enemy encounters that keep you in tune with your environment at all times. You have the freedom to approach any situation in a couple of different ways. If you want to sprint right into their face while unloading your mp40, the game won't punish you for doing that since there's no accuracy penalty for sprinting. Low on stamina? You can do a quick circlejump right into a full strafejump no matter your stamina level. If you want even more accuracy in general, then you can crouch (tightens the cone of fire immediately) and go for twitchy headshots. While you can't shoot while leaning around corners, you can use the mechanic to get a lay of the land without them seeing in order to optimize when and how you will announce your presence, a nod to those who like to think and play more tactically. Lastly, most levels can be completely at least partially stealthily, so there's a solid balance in place that appeals to any playstyle depending on your mood. At a baseline, the enemy AI is decent. They'll mix and match between being aggressive toward your location or staying back waiting for you to go toe-to-toe first. Some enemies have randomized placements that you'll only notice through repeated playthroughs. Some only appear if certain conditions are met, namely if an alarm is tripped. In addition to their base AI, a lot of enemies will have initial pre-determined routes to run at a certain trigger, which shows the effort to handcraft how they wanted different encounters to generally play out, rather than just dropping a couple guards into an area with no thought and calling it a day. As you go through the campaign, you'll pick up how it's got a little bit of everything and strikes a good balance of scriptedness and spontaneity in its design philosophy. It is precisely that healthy amount of randomness that keeps the game replayable, challenging, and fun.
