I put together a how-to for players to get over 33 million in a single HAAT team! Solo phases 3 & 4 with ease with this tutorial. Only 2 zetas required and you do not need awesome mods or awesome gear.
Hope this is able to help. Let me know what you guys think https://youtu.be/BlgDKYa6kjIhttps://youtu.be/BlgDKYa6kjI
