Played the training mission on my lunch break; it's definitely pretty different from The Dark Project, but the core concepts are the same. The bow-aiming animation is weird; the old one was much better, I think. And strafing feels super clunky and awkward, though that could have been in the TDP too, it's been a long time since I've played it.
Looking forward to doing some more lurking, robbing, and blackjacking skulls later.
I also found my old TDP disc, which I thought I had lost, but I can't install it on my fancy new computer.
