Greetings, members of ModDB. My name is Kenny, and I am currently the sole team member of the Zombie Swarm team. I originally started this project in about 2011 with a good friend of mine, but due to neither one of us knowing the first thing about putting together a source mod, it was doomed to fall apart. I had managed to piece together a few scattered scraps of content, but looking back, they weren't really of sufficient quality. Moving on to the present day, I now have much more experience working with the source engine, but I am still something of a novice. Filled with vigour, energy and ambition, I have since resumed work on my abandoned Zombie Swarm project files. At present, my plan is to replace all of the artistic assets and maps in Alien Swarm with novel ones. Essentially, Zombie Swarm will be a re-skinned version of Alien Swarm, with a couple of new missions.
Of course, as you can see from this picture, I have a lot of assets that I need to replace. In fact, most of what you see here are Alien Swarm assets, with the exception of the character model, her backpack, and the gun in her hand. (You may notice that her gun is the original, ultra-low poly MP7 model shown elsewhere. I plan to replace the model with a slightly less unsightly one further down the line, but it serves as a good placeholder for now.)
However, I just felt the need to share this picture to demonstrate the fact that I have the ability to get a model to work in-game. Now it's just a matter of mass-production. ;)
