I started fresh as a soldier on Insanity. On Hardcore I died maybe 1-2 times in the entire playthrough. On Insanity I've died atleast 10 times and I've done Feros and Noveria so far. I finished the battle with Matriarch Benezia this morning, good god I never thought this game was hard until this. I got warp'd like 50 million times and the asari commandos all rushed me. Garrus is a f@ggot he always dies, so it's just me and Kaiden. The first part wasn't hard. the part that got me was when you talked to Benezia and then she turns on you.. wow. I got rushed on both sides by asari commandos who all used Barrier and Warp'd the shiit outta me. One time I was on the last commando I had no health and both of my team mates were dead and I ran away desperately to gain my health back but got killed by a pistol. I was so mad, but I finally did it the next try. Took me about 7 tries to beat it.

Also the side quests are a pain in the butt. I've decided to do the main quests first so I can level up then tackle the side quests, those damn mercs are just too strong and theres too many of them.
