I bought this when it first came out and never got past the tutorial. Just wasnt into it at the time. Anyways, I was looking for something to play while Tomb Raider/ARMA3 Alpha is released, so I reinstalled it. Its a lot of fun. Kinda funny that I try to do stealth and do it well like 90% of the time, but then I think "there might be some good sh1t in that area...", and then I go guns blazing and kill everyone.
And man, I screwed up the dialog exchange with the desk sgt when I needed to examine a corpse (M5), and spent 3 hours trying to Solid Snake my way into the morgue. I knocked out so many cops I had my run of the place, but I couldnt get enough XP to upgrade my hacking to actually open the door. Finally gave up and did the other mission, and on the may I found a gun dealer and sold all the stuff I stole from the police. Anyways, the whole point of the M6 mission was to show me I could buy skill points.

So I bought 2 and just hacked my way from the sewer. So much easier than going in from the roof and working my way down. Kinda disappointed that I couldnt do the mission straight up at the skill level I had when I was given the mission.
Well, I did get through once. I threw a barrel at the trip wires to sound the alarm, so the cops came through the door I killed them and walked in. I thought I needed a pda with a code on it, or there was level 1 terminal somewhere to hack, so I wanted to do it right and reloaded the save. I was pissed for awhile, but in the afterglow of completing the mission I became impressed on how many ways you could complete the mission. All that time just because I wasnt sympathetic enough to that chump desk sgt. lol
