The sniper mission in Call of Duty 4 was superb. The first time you play it, having to sneak past enemy lines and face off dogs near the end. Then when you finally take the shot, running away with a crippled comrade. Best single player mission in any call of duty.

Half-Life 2- Can't remember the exact level, but fighting through the ruins of City 17 , trying to make it to this government building with Striders outside. Then when you finally get to the roof, having to take out a gunship. Eventually you end up back on ground level and have to take out a load of Striders again! Brilliant stuff!

The first time I played Deus Ex there were a lot of moments of trying to sneak past troops, planting traps, trying to find sniping spots. It was the first time I'd played a game of that sort.
