Some objective game modes put a heavy emphasis on PTFO so scorestreaks are much easier to get there. It's been like that before BO2, except some players would abuse the objective instead because they can't get them in TDM. That's why the number of MOAB (MW3) videos on YT on TDM are outnumbered massively by those who get them in KC and Dom, sometimes losing and quite badly at that.
If I'm playing with my groundwar team we get about 2-3 swarms per game easy. The most we ever called was 7 swarms. Dogs and lodestars come just as often.
I'm more of a lodestar dogs kind of player myself but swarms are cool too.
The trick to high streaks is the vsat. 90% of the time I get a vsat, ill get any streaks set higher then vsat.
no not like killing people with the objective. You still get points from your points streaks and things like the VSAT and EMP give you 10-20 points each for every kill a team mate gets while they are up.
You stack those two together and you get 20-40 points per kill that they make not including the ones that you get and you can easily hit the higher streaks like Loadstar, Warthog and Swarm.
the highest streak I've earned is the stealth chopper but to be honest I've got a curse when it comes to high streaks in all cod games if I keep them low I play great but as soon as I put something high on I can't hit a thing mw 2 was the worst for it as soon as I equipped the nuke that's it I couldn't get 7 kills to save my life
I am an avarage player with a K/D of 1.02 and I can get the swarm when I need to.
I only got it 4 times since release date (maybe 10 or so if you count care package) and it is do able.
It is a bit of a luck issue though. I've can get it by backing up my team and only going for the objective if I am not alone. keep close to your team mates to keep you alive.
I do still want to see a bonus playlist with just 3 scorestreaks.
UAV+hellstorm/lightning strike+stealth chopper.
This may be the only reason why I would want to play CoD4 again.
