call to arms is already a game
the waterfall in the last screenshot looks freat (freaking great?). It's a good use of entities. Can we see a vid of the falling water animation?
THe generator in the other shot is a bit iffy. Look in the bottom right, theres a pip pointing through the wall. I like the decal inside it though.
THe first shot, with the battle scene is ok. The hills look a bit steep in that shot. Kinda like there are alien blobs in the battle field.
Overall you're looking ok. Theres a good attempt being made at custom media, so well done.
You need to add some further light mapping, and consider the architecture of your level (like the waterfall... can you actually get to it or is it just scenery, if so isn't it a bit of a waste of map space and poly's?
anyway, looking forward to seeing where you're going with this.
its a fair start.
