=> basically Dragon is right about this. It's not a remake, it's just like the silent mod. Which TRIES to fix some common bugs in et/ Make a sort of new gameplay. For example the hitboxes in enemy territory are literately boxes.
Meaning you can hit players, by shooting a few millimetres of target. Some mods try to fix this. Most realistic hitboxes are the ones from Etpro (even they aren't really realistic!!). Silent mod however has the capability to almost exactly copy those boxes. So before we start this arguement, check it yourself. This how you can do/see it:
