How did it feel fighting a Phantom? That's my main concern with this game, how the combat against the Typhon is.
Everything else sounds great
I accidentally a gas pipe, and he died instantly. Before that he kinda caught me off guard while I was admiring a portrait of JFK. He chased me around the room for a bit, dodging around the various museum exhibits as I tried to equip my shotgun.
There's actually a stealth system in the game, similar to Far Cry 3/4 - or I guess Dishonored. You can even do sneak attacks for massive damage.
Right now, the melee combat against the mimics is pretty lousy. I'm beginning to realize the developers want you to put them in a weakened state by using the GLOO cannon, but it doesn't feel as intuitive as the Electrobot/Wrench one-two punch in Bioshock.
Ranged weapons feel quite good, although my only experience with them have been firing wildly into the air.
I'm actually surprised at some of the writing. I found a few books on cooking in Morgan's apartment that were vastly better written than anything in Dishonored 2. I guess throwing money at Avellone was a wise investment.
And yes - small skill tree spoiler -
there's a dedicated wrench skill tree.
