Every mission always seems to end in the same way.
I creep in, stealth-style, and take cover behind the outrageously convenient waist-high panelled fence. A quick burst of Penumbra Vision – just another name for that oh-so-common video game mechanic that lets you see through walls and solid objects – shows me there's five – no, wait, eight! – enemies between the exit and I.
For a couple of minutes, I sweep around the perimeter, executing a couple of stealthy takedowns, until someone, somehow, spots me from the other side of the room, tickling not only his spider-sense but that of every other soldier in here with me, too. Some big dude with an unfeasibly enormous gun stomps over to where I'm hiding, smashes down the fence I was crouched behind, and what do you know, it's fight time.
