I just wanna clear up a few things here. "Advanced melee" is just a term that was used for the DDR style melee in 1.2, the press arrows part of the game is now gone, but we still are going to have a different melee system than just simple melee, it wont just be simple melee, but it wont be cadence altering mini-games such as "press the correct arrows" like in 1.2, the new melee is going to be free flowing with the rest of the gameplay and there will be no waiting around. We're now going to have a new melee system which involves use of the SAM and 3 other melee methods. The only one of those melee methods you guys know about atm are simple melee, but there's going to be 2 others, all of which will be designed to keep the pace of the game steady and flowing. The SAM system will also be enhancing energy attacks, we're aiming to make melee and beams feel like part of the same system whereas before beams and melee (except generic beams) felt completely separate, the only reason you'd charge a signature beam would be to beam spam, there was very little chance to use it within a fight.
Hopefully that gives you guys a clearer understanding of what we're going for.
