I did a bit more work last night on the Metal arena.
I mentioned before that I plan to add various types of arena and blocks.

Wood,
Metal,
Rock,
Ice


What I've got looks OK, I need to work on the metal blocks a bit more though, they look much too plain.

Also, the level feels cold in comparison to the wooden level. This is a good thing I think as it gives a very different feel to the game, which means that it's worthwhile changing the scenery.

Depending on the performance aspects, I might add my procedural fire effect in the background.. and some particles (the arena is set in a steel foundry for the metal level)

For the ice arena, I'll be re-using my snow component from Guns Reloaded.. I might even use the water component too for the rock level. I'll have to see.

There'll be a new demo soon for people to give feedback.
