I know I'm the only one here playing this, but I don't care. It's great.
It's really just more of the same, but given that the last one was pretty much my GOTY for 2016, that's absolutely fine by me. It's more polished-looking, with fancier lighting and stuff, and also adds things that the community was frothing at the mouth over not being in Hitman 2016 - principally the briefcase, which I have yet to use even once.
As well as all the new levels, there's also the Legacy Pack, which is almost all the levels from 2016, but rebuilt with all the new stuff - so you can hide in foliage, smuggle stuff in a briefcase, and so on. If you already have the stuff for Hitman 2016, then you get it here - there's no re-buy.
Things you've unlocked don't carry over, though, so I've probably spent more time in Paris than Miami, as I work my way back to having all the shit I had before (with the main focus on poison vials, the keycard scanner, and a silenced sniper rifle - at which point, I might actually use the briefcase).
I'm still trying to mop up as much as possible in each level before moving on - while I'm happy to hop around the 2016 levels a bit in the name of gear, I'm trying to stick to my episodic guns on the new levels, and only move on once I've hit level 20 Mastery; I tried to get all the trophies, too, before, but some of them are fucking hard, including completing levels on Master, which I haven't dared even attempt yet.
As with Hitman 2016, the prologue is free - but as with Hitman 2016, it's the ICA training facility, so if you played the demo of the first game, there's not a lot different.
So far I've only played the pre-release version of the Sniper mode in single-player, and only had 2 goes in the 1v1 competitive Ghost Mode, but each of them only seems to have one level so far. I know they're adding more Sniper levels down the line, but Ghost Mode is still labelled as "Beta", so I assume they'll expand it to the rest of the locations at some point in future.
It struck me this evening just how different this game is to pretty much everything else that's huge at the moment; as the industry seems to be going all Ubisoft with their big, open worlds covered in sidequests and collectibles, IOI are sitting here, quietly focusing on their small, intricate clockwork sandboxes, and I greatly appreciate that.
TL;DR: Hitman 2 is great.
