I have quickly had to ditch my 'no kills' attempts at various missions because it is just so darn tough. I can usually do the primary stuff OK but then I'll climb onto a roof to plant some C4 on a comms dish and they'll spot me there. So now I'm trying to remain stealthy... but I don't mind doing some murdering.

There was a great moment earlier when I had to neutralize a particular person who was driving from one point on the map to another point. I cut across the hills on my trusty steed just beyond an enemy guard post he was going to drive through, took out a few guys, and then I heard the car approaching in the distance. Set some C4 on the road, drop to the floor, roll out the way and detonate just as the car goes past for a perfect hit. So cool, so much fun.

Still think this game feels more like Far Cry than Metal Gear Solid... but it is quite a good Far Cry game at least.
