So there's no guarantee eh? I'd imagine most servers would run with team balancing on. THIS was the primary reason we didn't end up playing Killzone together. Sucks to hear it hasn't been updated or fixed.
Are you talking about Skirmish mode here? I remember when Guerilla removed the ability to boost via bots, but yeah, just playing online with friends against bots would still be a decent time if it was available.
I've been getting the urge to try it again because MW2 just feels like there is too much junk to it. So many perks and equipment combos that the balance from COD4 has been completely lost. That and I love the way Killzone controls, even if it is jarring to many.
