It is too easy to get Spawn Trapped and Camped on Container City. Same problem in Gears of War 3 Beta with maps like Trenches. There needs to be a way to flank out of spawn on Container City.

I concur. Not because its done to me, but because they only have 2 spots that are both watchable from any area.

For the security to get spawn trapped you mean? I think it's legitimate tactic in this situation. They are not actually spawntrapping, just holding a good line of defence.

It's a spawn trap because the Security can't leave their spawn without dieing. Any other situation is fine by me, because Security would have more space to work in, but the Security should have a high ground exit to that area as well.

This is what I am saying as well. Spawn Trapping is more of an exploit when the spawning team can't leave the spawn area to even formulate an effective strategy. I've been on both sides of the trap and neither is very fun. The side trapping gets marginal experience as well, so its not like there's a huge bonus besides winning. Its like a wasted match in a way. I was looking at the back area near the Security Command post, and it would be cool if there was a way to open up a hidden passage.

There's 2 exits, well-spaced to require separate defense to spawn-trap. if you're getting caught there, you're doing something wrong. Or the other team is REALLY good.

Last time I played CCity, I was Security, and 4 of us spawntrapped the Resistance team for a good 2 minutes before they got organised and broke though.

While I hate when that happens on this map all I can say is that a well placed flash bang when leaving the far exit blinds those fools picking us off....done it more than a few times.

True but
A. How would this affect the map
B. Where would you put it?

The problem is the devs have designed the map for you to be able to counter Security pretty easily on first spawn, but if it fails and they set up well you're completely screwed.
I've never been spawn trapped when I've been there from the start, but no doubt someone will counter me eventually and it will work out the way it did when I came into a game late.
Utterly trapped, mines make it impossible. 8 v 8 with the health you have means it takes too long to frag an entire team from an inferior position.

Honestly two exits with eight people who have a height and visibility advantage, the possibility of tubes, turrets, flash bangs and mines?
LOL what a joke.

Actually played a game whilst I was being spawned camped at CCity and I honestly just ran through, sprayed and prayed. It's called diversion. Sure you might die, but by you hindering their "camping" they will get sidetract, thus allowing your team to advance. That one move can turn the tide of battle.

Every time the Resistance trys to spawn camp you there, send out two teams of 2-3 people, one left toward the gate and one right toward the section you can climb over, the others should lay down cover fire preferably a heavy with a LMG/Gatling gun or a couple of people with scopes/good range weapons. And follow the people to the gate. Now once there, immediately send an operative and a solider to open the side passage on the left of the gate. But before he opens the gate they should both lay down fire from that gun port in front of the door.

Easy.

I used to have this problem until I found out something. Give 2 heavies every boost possible and make the heavies soldiers with armor piercing rounds and kevlar. They mowed down everyone with their MG's. And with the whole team spawning, putting up that HE was too easy.
