We haven't really heard much about the PSP version of James Cameron's Avatar since it was first announced to be a majorly multiplatformer title. IGN is reporting that the October issue of PlayStation the Official Magazine will be carrying a small feature article on this game's Sony handheld version.
Said the mag, the PSP version will have the player use the character of Na'vi, blue-skinned, wide-eyed creature, following his story after he leaves the village destroyed by the RDA. There will also be a PSP-PS3 connection, and players will be able to transfer "Effort Points" from portable to console. This will in effect give your characters a boost.
That's not much information right there, but it's still better than nothing. Hopefully we'll get more of these platform-specific news bits for James Cameron's Avatar.
