re2 hacking conclusion: if you hack yourself the items every interaction in the demo area works, you can even blow up the C4. There's a few extra rooms to explore that way but nothing big. Not sure if/how the sliding bookshelf puzzle works in the remake, but they slide. The STARS Room has been patched out, sadly, it looks really cool in the dev streams.

There seem to be a ton of infinite ammo weapons (including an infinite durability knife). There's a D-cell battery that I don't think was in the base game. Four pictures to develop (only one accessible in the demo). Leon will gain a lot of inventory space pretty quickly, we found like four sidepacks
It's pretty obvious that this demo is simply the build they made to show at cons, which is probably also why it has the timer. They added notifications every five minutes using Steam Achievements for a reason lol
