A while ago I asked for advice on completing my insanity run-through on ME1. Well I finished it today, so I just wanted to say a particular thank you to everyone who gave their advice, particularly the all-knowing Marolf, and also to make note of what worked for me in case it helps anyone else.
1) Wrex and Tali were my go-to team, both equipped with HMWSG X shotguns, both with Kinetic Coil X, Scram Rail X, High Explosive Rounds X.
2) I maxed out both Wrex and Tali on their shotgun points, plus also maxed out Tali on AI Hacking.
3) I was playing as a soldier, and was using HMWP X pistol most of the time, with Kinetic Coil X, Frictionless Materials X, and Inferno Rounds X.
4) I'd already completed a game with my Engineer character, so was able to pick Electronics as my bonus skill for my soldier. I maxed it out and it was very useful.
5) I maxed out Electronics, Fitness, Assault Training and Combat Armor, if/where each was available for my Shep, Tali and Wrex. Thus maximising protection where possible.
6) I used Colossus X Armor for the whole team, with Medical Exoskeleton X and Energized Plating X for everyone. I used Colossus X Medium for my Shep as I hadn't come across any Heavy yet, but it worked fine.
7) I saved a LOT. Especially during the Mako sections, I saved after every battle, and if necessary, backtracked a bit and then exited the Mako temporarily in order to be able to save.
8) I tried not to get greedy when fighting from the Mako - I'd do as much damage as I could with shields intact, but as soon as the body of the Mako started taking damage, I hopped out of it and fought on foot.
9) Already knowing the game fairly well, on the most difficult battles I'd immediately direct Tali to hack the most troublesome enemies.
10) Tali Overload, Wrex Carnage, Shep Marksman was the best combo I found for taking down Krogan fast.
I'm sure for a lot of you this is really old hat, but I'm still inexperienced enough for it to mean a lot to me. The sense of achievement I got from completing Insanity... well, my heart sings.
And yep, I know that ME2 Insanity is 10 times harder. But now I've done it on ME1, I know I can eventually do it. It's a confidence boost, and an incentive to keep trying and improving my skills, little by little :)
