You might consider downloading some images of roman legionairres and pasting elements over the model texture. It wont look professional but it should get the job done for your purposes.
yeah I will believe it when I see it. Even then I doubt I'll use them primarily. Crytek has blown Valve out of the water. Not to mention countless other middleware developers.
What I would have also liked to hear is "we plan to stop breaking your codebase with SDK updates"
The Bad
Hammer is archaic, it needs a lighting preview badly, the sourceSDK launcher has a habit of breaking the day you planned to get all your stuff finished for a new patch, but the worst thing is the art pipeline. Getting a model into the source engine with proper looking materials etc...
