How to unlock the Purple Demons achievement in Saints Row: Gat out of Hell - Definitive Guide
Once you have unlocked the Summon power it can be selected with . The first power up you get, imp will work fine. Simply call in imps and let them go kill demons. This can be upgraded so that you can call in four imps at once. There are also two other elements you can unlock by doing the alter missions. If you complete the correct alter, you will earn either tower or titan. I used a combination of imp and tower for this and it came naturally while completing the game.
This is earned for using the Summon ability to summon demon helpers to kill regular enemies. Husks do not count toward the total, but I believe all three of the elements of summon count toward this total, as long as the kill is actually performed by the summoned demon. Using the “Detonate Summoned Imp” ability does not seem to count toward this. Simply have summons kill 100 total enemies to earn the trophy.
See "Plague of Gat" for detail on grinding this achievement.
This can be any combination of Titan, Imps, and Tower kills. You will get this easily on the way to completing all the challenges. To have a summon ability active tap , continue to tap until you have the summon you want and then press to summon them. You need to let them run around mid battle and be a little patient with it, especially with the imps. They seem to be extremely bad at picking a good target.
