Heart Of The Monster Tips and Strategy

Use Ranged Attacks Whenever Possible

Enemies here deal a lot of damage, but are all susceptible to ranged attacks. Take out the Plague Drones and Purge Keepers whenever they are present, as they can deal continuous Gamma damage. Focus on dealing with the ground units via ranged attacks after clearing out the drones.

Master Dodging Techniques

This mission will feature very difficult enemies, including Prime Aegis Synthoids and SPIN Synthoids. Mastering when to dodge will be crucial to give yourself a good chance of going through this mission easily.

Heart Of The Monster Boss Guide

Abomination

This will be one of the few times that you get to battle Abomination again. Since this is an Iconic Mission, this fight will progress the story of the Hulk as he battles a foe made possible thatnks to the gamma experimentation done by Monica Rappaccini.

Most of Abomination's attacks focus on powerful, but slow hits, as well as radial attacks. He has his own version of Thunderclap, and will focus on repeated ground smashes that sends shockwaves. If you try to get near, you will be hit multiple times.

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. If Abomination turns his back on you to focus on your teammates, launch in combo attacks and then quickly dodge back to resume attacking from range.

If you brought Ms. Marvel in your team, have her use Healing Spirit whenever possible to ensure you survive in this long battle. If not, use healing packs located all around the stage when your Willpower gets low.
