It's picture time (courtesy of MS Paint)! Here is an approximate layout of Dr. Swol's compound:
The three dots in the bottom middle are Pete (brown, on the wall), Pikachu (yellow) and Melkor's Ghost (grey). Red dots represent foot soldiers. The two dark grey dots on the right are the steel toads (only one has moved, so far). Ward is blue. McGill is green.
At the moment, Pete is not close enough to any foot soldiers to actively engage them with his web. His choices are:
1) Engage the two foot soldiers approaching from the outside (bottom left) which would require him to wait for them to arrive or move in their direction along the outside of the wall. Pikachu and Melkor's Ghost can voluntarily engage them, as well.
2) Help Pikachu up and over the wall and go inside the compound. From there, the group of three can go left and attack the lone foot soldier, go straight and hide in the large building, or go right and attack the 8 foot soldiers waiting inside the gate.
3) Run back to the gate from the outside and help Ward and McGill.
4) Something else that I haven't thought of yet. I'm sure there's many more things to be done or tried to do, but there are only three places to get in a fight. (Four, if you count the inside and outside of the gate separately.)
Finally, I'll attach the picture so Spiderman can see it, too.
