A few new game elements were introduced:
[1] Mobile Suit Parts Customization
We already knew we can play the new RX-81 Gundam, and we also knew we can swap weapons & loadouts of each mobile suit. But what we didn't know was that player can also swap various body parts to meet the demands of the upcoming mission. So if you want a new better shoulder for your MS...is possible. In preparation for an underwater/amphibious mission... you can add modifications for better underwater performance. Player will also get to change the colors of various body parts to create their own look & feel.
With so much customization features, I can imagine myself spending loads of time just messing with these features. Here are some screenshots of what I am talking about:
It was also announced that there will be an underwater scenario. It will be a Federal Force's mission scenario, where the underwater stage will be a sub-phase of an industrial area defense mission.
Performance of mobile suits underwater will behave a bit differently, so players will need to make sure their mobile suit is outfitted with underwater hardwares.
Here are various screenshots of the underwater scenario, and a few displaying a federal mobile suit going up against a Zeon mobile armor.
