XCOM 2

Missable!

To get this trophy, you must kill all three alien rulers, have Dr. Tygan autopsy their bodies, then create the following suits of armor from the Proving Ground: Serpent Suit (from the Viper King), R.A.G.E. Suit (from the Berserker Queen), and Icarus Suit (from the Archon King). Each of these suits has a unique ability. You will need to equip three soldiers, one with each suit of armor and use all three unique abilities in the same mission. The abilities must connect with their target to count for this trophy.

The unique ability for the Serpent Suit is Frostbite, which freezes an enemy in place. The default accuracy for this attack is not very high but it only has a two-turn cooldown. The R.A.G.E. Suit has Rage Strike, which is a melee attack with only one charge per mission. The Icarus Armor has the Icarus Jump ability, which simply allows the unit to reach the top of ledges and structures without having to climb. Use all three of these abilities successfully in the same mission for this trophy to pop.

This trophy is technically missable because you could lose a soldier wearing the unique ruler armor.
