You are looking at a very usefull little lowpoly scene called:
The Last Barrel Toxic Waste.
It contains a set of lowpoly explosive barrels in different conditions and aging stages.
Beside its functionality as monument of economic criticism, it contains a set of oil barrels, that vary from brand-new to used and exploded. In addition it contains debris elements and textures, which makes this bundle a huge timesaver for any game project!! The barrels come with a rather performance friendly polycount of 712 tris/barrel and largely scaled high detail textures of 2048x2048 dimensions. The different aging states of each texture make up for a good variety with rather little effort and the destroyed version can be directly used as debris model, after the barrel exploded. The debris, concrete and steelbar textures are tilable. Putting all of this together, this scene makes up for a very valuable asset and can help you a lot in your development process. Textures can be downscaled of course, but are suitable for closeup renderings in this resolution.
The renderings are done with the Maya Hardware 2.0 to give a better preview of the actual in game result.
In addition, I will throw in a small HDR Reflection map, as well as a tilable concrete floor textures, as you see in the presentation images.
