Combat is a wee bit annoying at the very start, with small enemies skittering about, but once you get one of the guns with a bit of spread, that ceases to be an issue. These enemies don’t do a lot of damage anyway, so it is nuisance factor more than anything.
The Gloo Gun and the rubber dart gun are really tools, not guns, and shouldn’t be used on enemies.
Ending is great, but definitely marmite.
I’m in the camp of admiring but not loving the Dishonored games (finished both); loved Prey and it’s DLC, though I played the demo for Prey and thought it was not my cup of tea and put off buying the game for a long while.
Edit: one slightly frustrating aspect is that the first several upgrades are very underwhelming, but stick with it and you’ll be rewarded.
