The game showed me that I'm very poor at preparing for personal mission but that I'm really lucky resourceful.
One mission was an assissanation against a Glitcher officer in a ship full of shielded enemies and sentries. I had only 6 charges of crashbeam for that mission plus a silent shotgun as my main weapon, I also bought a Brick pod in case the target was on the side of the ship. In the first room, I critically failed a spot check and tried to gun down a shield guard. He returned fire with his shotgun and throwed me back into space. Back in the pod, I knew that the officer stayed along the hull on the other side of the ship so I aimed the Brick there. I missed the target, but ended up hitting the 1 room-wide corridor linking the cockpit and the thrusters turning the alarm off. I docked at the severed part where my target was and while I was planning my infiltration, the wreck flew by an allied station that fired a missile at the room where my target was. Dead is dead. Mission Accomplished! Let's retire.
Another one was another assassination against armoured Foundrymen. I had three grenade launchers and a key cloner. I fumbled with the grenades and end up with all the guard of three guard posts waiting for me at the docking bay. Since the ship was flying near a liberated station I go back to buy a AP silenced rifle and another AP gun for the ammo. Back to the ship, I realised that there was no way for me to go through the guards. There was a locked dock on the back of the ship left without guard because of the commotion I made earlier. So I clone a key, docked at the other entrance and passed the guards. Short on time, I was able to get into position to launch a grenade at the pilot. The explosion attracted more guard and opened a way for me to get to the target. After dealing with light resistance and dodging a trio of turrets, I got to the zone where my target patrolled. I waited patiently in a windowed room until my target appeared. Then I shot the glass and accompagnied him in space just so I could watch him suffocate.
