In Deus-Ex, I'm trying to play a run wherein the main character is a cruel, merciless cyborg who cannot distinguish between friend and foe. Basically, everybody dies.
Things seemed to be going well in the first mission, where one of my comrades greeted me after I annihilated the enemy's leader and I proceeded to unload a 12 gauge into his lovable face, causing him to keel over and die. I stole his assault rifle and went down the stairs to my next friend, who told me what a great guy I was. I smiled and agreed and stabbed him 37 times in the chest. The only problem is that this didn't kill him; it caused him to get aggravated at me and shoot me with several poisonous darts as a form of comeuppance, rendering me quite dead.
Are there some comrades who simply won't die and who will endure whatever pains I put them through, or do I lack the necessary firepower to eliminate them at this point?
