Rockman Xover received an update today, ushering in the all new World 7. This time around the bosses are from Mega Man X8. We have Optic Sunflower, Avalanche Yeti, Burn Rooster, and Bamboo Pandemonium. Take down those four and you'll face Sigma. Lumine's a no-show, unfortunately.
In related news, the armor you get from this update is a very green Over-8. It's a dual wood/wind type, strong against electric type bosses. You can see it along with more images after the break.

"Last, Xover also brings the “Irregular Burst” system. Normally, Battle Memory cards have a limit to how much you can level them up and improve their stats. However, by combining identical cards, you can surpass the normal leveling limits and make them even stronger. In honor of this addition, players currently have a chance to receive “Golden Wily” and “Silver Wily” Battle Memory cards when they log in."
Hankering for even more images? Rockman Unity's got you covered.
