Finally finished this.
The Engineering-floor felt more dark and ominous than I remember it, but it's far less of a deathtrap than the original was, which was full of Assassin cyborgs waiting in dark corners.
The Security-floor was shit, as in the original, but even more so. That they added a door that seals off the rest of Citadel Station right at the start was a disappointment, especially since there's no Recycling Station around.
The Bridge feels like a Borg Cube. In the original it felt techno-organic, but that was probably too hard to pull off with hi-res graphics. I cheesed the autobomb-maze in an amazing manner: The puzzle board had the relay going in an ever-expanding spiral, meaning the power travels through every square of the board. I set up the board so that the innermost piece was the last one, flicked it on, then rollerbladed towards the exit ASAP while the power routed itself through the board. By the time the message came that I had lowered the forcefield (which triggers the autobomb spawns) I was already racing across the laser bridge.
As Citadel Station was destroyed before I could even begin to look for a cargo lift outlet, I lost half my arsenal. Fortunately I had planned for this, and had several hundred rounds for the Skorpion and Mark III-rifles. Those ended up carrying me all the way through the bridge, right to the third Cortex Reaver-fight (there were only two in the original) where I drained both guns of ammo. That was when I remembered "Hey, I brought the grenade launcher along!" *THWOOP* Cortex Reaver bites it.
Once you jack into cyberspace on the bridge, the game is pretty much over, it's just a victory lap in cyberspace... where you're confined to your legs. You can even run until you're exhausted! The UI goes off on a coffee break, so imagine my panic where I holstered my 'weapon' and couldn't bring it back... until I hit the 'holster'-key again. Anyway, boring and useless sequence, but the outro is good, especially the synth-feast of a tune borrowed from the film 'Hardware'. I felt for the Hacker when he slumps down there at the end.
Overall, I think this is a good remake... of a game that (deep breath) wasn't that great to begin with. Don't get me wrong, SS1 is a good game, but is also plagued by many things (the groundbreaking but sluggish UI, for a start). A remake 30 years later has plenty of space to fix many of those things, and at least the remake accomplishes that much, especially in the graphical and UI-department. But at the same time there are some extremely boneheaded decisions taken with the remake that no sane person should be doing in the 2020s (inventory management, the recycling crap, the idiotic enemy spawns, inferior audio logs, less atmospheric) and the remake ultimately ends up highlighting the bad parts of the original. At least they made the skates fun.
The weapons... were a joke. They felt so generic and bland, the only one that stood out was the Magnum because of the PJOING-sound it made when firing. The Railgun deserves a mention not for being stylish or an effective weapon, but for easily having the longest reload animation I've ever seen. Enemy combatants were likewise a joke, only Diego and the Cortex Reavers proved to be a challenge... mostly for them spamming explosives. The first fight with Diego is cool because of the 'arena' and how he's coming at you with lightsabers, but for the others it's just popamole cover-shooting... to a point, as most of the cover can be destroyed. I held on to whatever proximity-mines I found, as I was hoping to be able to cheese Diego as in the original, but the only time that was possible I forgot to use them.
The only audiologs worth a bother were the new ones where they patch up some plot holes in SS2 (the wormhole and why SHODAN is wearing a kimono in the boss fight) and a single audiolog on the Security-level where an executive is sending a message to his daughter: "I wish I would have looked at Saturn more, it's so beautiful." That one actually had some real emotion in it.
Will I play this again? Maybe, but it'll be YEARS down the line. I've done enough System Shock for one lifetime. It'll be interesting to see what the modders can do with this one, though.
