A fast, easy to use, free, and community supported 2D game engine

It's only an idea, but I am wondering if it is possible to accomplish this using Cocos2D, or if I would need a 3D engine.
A character in the center of a stage, looking downwards towards the ground. Enemies come in from all sides (front, back left, right). If the character were to rotate 180 degrees, so that it would be looking 'backwards', but the point of view would rotate also to look at the enemies behind.
Like this? http://gameofdadead.com/screenshots
Yea, I would have thought that is possible with cocos2d. You'd just need to workout the character's viewpoint and then workout which enemies are in that view port and show them.
Take a look at the 'diagram' below:
Key
C = Character
E = Visible Enemy
G = Invisible Enemy
\/ = View Point
Looking 'UP':
\ /
\ E / G
\ /
\C/ G
G G
G
---------------
Looking 'DOWN':
G
G G
C G
/ \
G / E \
/ E\
/ \
---------------Is this the sort of thing you're after?

ok so that didn't work sorry, I'll try and do an actual image later.

@AggroPanda, I changed your asciiart to a code block which makes it easier to read.
@Codemattic, thanks, how do you add a code block so I can use them in the future, cheers.

@AggroPanda Yes, exactly what I mean. So I am assuming I would just have an instance variable for each enemy that tracks it's position, then calculate whether or not that point is or isn't in view?

@AggroPanda - use backticks on their own line before and after code:

This is a code block
Monospaced code that wont wrap around

@liquidfire theres lots of ways to check, one approach would be to cycle through objects on screen, checking there position vs the players, getting a degree reading from that and checking if it lies within the current degree range of your arch. thats how i'd do it anyway
@abitofcode 3 if you count the one about how many conversations there are in the post :) lol
theres lots of different approaches to this.
Ive made two prototypes in cocos2d thus far and have used two different methods
The first, the character stayed still, and if i wanted him to move up 1 pixel, the map moved down one pixel instead, the map was a layer, and all of my sprites were children to that layer except for the player. This meant that the entire world moved. Enemys could also independently move across the layer.
I got some fps issues with this approach, but that i think was due to my ignorance regarding spritesheets and there usefulness.
With your game, its a big visual feature to rotate the map or the player, personally, id rotate the player i think it'd be easier and cause you less problems in regards to co-ordinates on the stage moving
