Infinity is not a game that I've played much of. Regardless, I have picked up some of the resin bases that are specifically designed for the game. In the image is a 40mm urban ruins resin-cast base - one of a set that I own but have not yet painted up.
The first thing that stands out about these bases is the flavour. The hexagonal tiles are moderately uncommon and will certainly give a "zing" to any miniature mounted on it. Painted well - probably with white, or off-white marble for the hexagons to contrast a darker colour in the grittier regions - these bases boast a great level of detail. This particular piece features a rifle that has been left on the ground, plus spent ammunition rounds and a small pouch. Coupled with a post-apocalyptic feel for the damage appearing on the surface, these bases make a great impact in warhammer 40k (especially Tau or anti-Tau themed armies), or other sci-fi games / roleplaying of a similar ilk. The quality of casting is high and I can honestly recommend these bases to anyone looking for something a little bit more left-field than the regular bases.
[Disclaimer: I'm not affiliated in any way with Infinity or the resin bases that have been produced to couple with said system. I was not given these bases as a gift - I bought them in a store on a whim as a regular customer!]
