City Under Siege Boss Guide

This will be one of the few times that you get to battle Abomination again. However, this is just an Abomination clone, and bringing Hulk here won't progress his back story.

Avengers City Under Siege Boss 02.png
Most of Abomination's attacks focus on powerful, but slow hits as well as radial attacks. He has his own version of Thunderclap as well.The main strategy here is to stay away and use ranged attacks. It is highly advisable to use Iron Man or Black Widow here to quickly land in attacks from range.

Abomination Boss Battle Guide | How to Beat Abomination

Knocking Abomination off the Building

There is a possibility of sending Abomination out of the ball park - literally. Should your character use an attack with a high knockback chance, you may actually send Abomination off the building and score yourself an instant kill.

BE WARNED, however, as this can also happen to your allies! If it does, your hero cannot be revived, and you are left with just three remaining members.

City Under Siege Chest Locations

Chest Locations
In the first area marked with a "?", there is a switch you need to open to access these two chests.
Similar to the first one, just head to the second "?" area and open the room via a switch. Get these two chests inside.
Just before you turn into the room with the elevator, there's a chest to the side which is easy to miss.
In the room before you fight the Abomination, there's a central room which contains this chest.

Note that dark brown / bronze colored chests may shift locations or not be present at all during a mission.
