Finished Citadel, which is a pretty good shooter, with interesting mechanics.
Aside from the usual double jump, and aim down sights, that we have come to expect, you can also quick reload, which drops the previous magazine with all its bullets inside, that you have to then pick up if you want your bullets back.
Other weapons require you load one bullet at a time.

Just started Beyond Citadel, and it also introduces new mechanics, where the empty magazine needs to be removed first, and the gun needs to be cocked after reloading.

Sounds tedious, but actually pumping the shotgun for each shot feels both exciting and cool as shit.

Also, peak aesthetic.
