I think this is an interesting enemy, I really like the fact that you can die from suicide as well as normal damage. Unfortunately this can only really catch you out if you are new to the enemy. But I thought to show you some things...
1, Being killed by suicidal influence.
2, Resisting suicidal influence.
3, Not resisting suicidal influence with no ammo. - Having ammo in reserve will not get you killed either as you're not forced to reload.
