The Crysis-2 4" figures are good figures, I thought. Modest value too--although they are $10. They do come with extra squad weapons with tripod stands, or added pistols and extra bits--depending on the figure. Detail is very good, and articulation is comparable to the weaker POC figures.
They DO expand the weapons choices for Joes ( or COBRAs, I suppose) and the Nomad/Alcatraz figures make for interesting counterparts to the Accelerator suit Joes. The Cell trooper is a kinda funky heavily armoured trooper, and he could work as a Joe or a COBRA.
Unfortunately, the figures do NOT have peg-holes in their feet, so standing them can be a challenge. Poster putty might be the order of the day here, or make them a vehicle crewman.
I found mine at my LCS ( local comic shop).
