LOL. Think of it as Tactical Immobilization.
Again, its nothing to be taken too seriously and is all for fun.
If you get a squad of 6 and branch out of that room in hijacked and set everyone up right you can go in and pub stomping. with some experience your squad will be full fledged "spawn trapping". It would be harder on a bigger map. But of course im not telling you anything you dont know.
I would still try your tactic for fun if I had BO2 yet.
You should add me and come play MW2. Ive never had a team until I went back to MW2 but i have to cause of hackers. Literally aim bot, constant UAV and wall hacks all combined alot of times.
We have to "extreme camp" to even stand a chance. Noob tubes are a must to with some people set up with spray weapons or Shottys incase someone creeps up on out flank. Claymores and Scavenger as well.
Believe me its not boring.
I dont have MW2, but I can get it. I've never played MW2...haha, I started COD with BO1. My friends that used to play and I had an extreme camping team which was pretty fun, not boring at all. While we didn't have the shield or trophy system to keep us alive, we had 2nd chance and tac inserts.
You might be ok I just wouldnt attempt it solo. Honestly tho im going to tell you to not even waste your money especially since you would be going in with no knowledge of the game.
If I manage to save up enough to buy BO2 and all the DLC for before the new title. Im down try your strat out.
Extreme camping? Thats right up there along with Extreme Ironing, Extreme bird watching and Extreme watching paint dry!
