Appearing on the other side of the portal, Loki first was to move away from it so to not block it. When a sufficient distance away from the portal, Loki looked around to get his bearing in the large hallway, between the chaos. Spotting the door that lead to the room the royals were in at the northen end of the hallway, Loki motioned Rita to go there. Making his own way there, Loki heard Jessica's message, and reached for his pendant, answering, Prepare to extract us when I give the word. That is all.
There were twenty guards between Rita and Loki and their targets. They formed a position that blocked off the hallway, with ten guards in the front, crouching on one knee, and the other ten behind them, remaining standing. Two guards in the rear focused on raised a barrier infront of them, while the remaining eight at the rear launched ice spikes at the zombies. While they didn't aim for either Loki or Rita, given that they couldn't see them, they were in the line of fire.
The other ten guards at the fron stood by, channeling magical energy in preperation.
Ness' shot was dead-on, the bullet passing through the visor of the guard's helmet, and leaving a bloody exit wound on the back. Needless to say, he wasn't able to finish requesting back-up.
Given that since Jessica was no longer shrouded, the portal could be seen, plus the earh using zombies having come through, the 24 guards on the southern end of the hallway had ample time to form defensive positions, using combined barriers to block the incoming attacks of the zombies. Six guards drew their swords and charged at the zombies at varrying speeds, and when in range, worked to surrounding them by attempting to drive the zombies closer together after the attack from the guard at the northen part of the hallway would hit, doing this with slashes that wouldn't prove very damaging. With their comrades engaged in melee, the remaining ten of the 18 remaining guards stood by and waited for the zombies to be driven closer together. The other 8 launched medium-sized ice spikes at the earth-using zomies, all aimed for the center of mass.
The earth-using zombies had trapped six guards in the side rooms by blocking off the door.
