MGS is the only stealth game I actually played, liked, and beat...
But when I play online shooters I try to be as stealthy as possible. I like to see them and they don't see me... Using cover, walls, angles, setting traps, etc.
Usually all that is in Gears of War... I guess thats why I play that so much. I'm pretty sneaky in that shyt. I also set traps for other teammates by pretending to be "bait" while the other one gets the kill from the side. Me and my boy actually came up with a name for that, we been doing that shyt since Halo 1
But I hate when cats on my team just run up and blow the fukking cover though. Like I'm behind a wall planning to pop this nikka and some dumbass on my team runs up behinds me then runs out into the open, blowing the surprise attack. Or when someone is supposed to be watching my back and isn't paying attention or say shyt
