Help me get into University.
You might be better off asking around a modding community maybe?
The nexus forums might be a good place.
The modding in CoH is pretty limited.

Modding is not something MMOs support outside of UI design, due to the client/server model of the game assets. If you are looking for tangible things you can make and show the college you are much better off with stand alone games, or things like Little Big Planet where you can do some quasi-level design.
Well, you *can* mod CoH, but it is frowned upon... and only appears client-side. Back in the day someone did a really impressive Superman by swapping out one of the chest details for the big red S and did different boots, I think. I can't recall if they did a new cape as well.
The Alt Alphabet ~ OPC: Other People's Characters ~ Terrific Screenshots of Cool ~ Superhero Fiction
Modding is generally frowned up around here but there do seem to be some exceptions...
some people have done it as a way to "fix" things that the devs don't have the time/patience/resources for
(like reorganizing the chaotic mess of the power tray icons, silencing noises that play in a constant loop and aggravate, map packs etc).
That aside how about a more common sense approach? I would think you can achieve what you want without
breaking any rules here by just using the Mission Architect. Want to make custom enemy groups? Go right ahead.
Want to show off that you have a good grasp of pacing in a self designed arc or TF? Have at it... no modding required.
If you want to really blow their socks off then I suggest running some of the Developers Choice
awarded arcs and seeing what the best of the best playermade content is like and then go from there.
Cheers.
Basically the whole gist of me getting university is that I need to prove to the guys who run the course that I have a passion for games and would be willing to stay the course. They are clamping down on the number of people that they admit and I need to show that I am one of them.
To do so they suggesting getting back into modding, this was something that I did a bit of on Jedi Knight 2, reskinning models and such (I unfortunately have lost all of the work I did so that's out of the window for showing them, not that I'd want to as they were pretty terrible, heh). I need to know if that is viable for this game. I could choose any number of other games but I'd rather work on a game that I love through and through and this would be that game. I've seen pictures where people have applied the male muscle texture to women and such and I need to know if it's possible (or even allowed) to be done.
I was thinking of starting of small just doing new body patterns and what not. Any help that anyone can give or advice would go a long way.
I'll also be doing some concept drawings of revamped enemy groups and character redesigns, I don't have any at the moment and even if I did I couldn't show them as I broke my scanner and looking at getting a new one. I've got a lot of ideas, 2 of my favourite villain groups in particular. I've also got ideas for level designs and a task force in mind as they like that sort of stuff, where I show an interest and knowledge of things like level flow.
Also if anyone has any experience with this sort of course then I'd like any advice for what would really impress the tutors, I want to blow their socks off as doing this sort of thing for a living is my dream and I need to make it happen.
