PTDE can be played above 60 through DSFix with minor physics bugs.

Remastered cant as all the logic is tied to the fps.

What did they do to dead cells?

Probably the way they used to do things, provide the server hosting tools to the community.

Think like TF2 and CS:S.

There’s plenty (But not all) MP games that can do that.

There are already PS4 emulators. Though they’re extremely early and work a lot closer to how Wine/Proton do rather than traditional emulation IIRC.

The MTX were removed for DD:DA.

Only the original release of the game on Ps3 and 360 had the mtx. So in a way they improved things only to shit it up again.
