Currently, there is no concept of "exp". Your prgression is determined by the weapons and armor that you have or can create. That said, I think some "fast forward" mods have already been created. Some people want to use them after wipes and such. From the perspective of a beta environment, it seems conterproductive to impoving the game.
Kinda sad, isn't it? They'll lose all the pleasure of exploring and crafting, am i wrong? I mean.. "Let's play this game, let's have all the best items immediately".. and then? And what about all the random things, spawns...when we all can create custom planets and dungeons....?
