Print out this screenshot and stick it to your forehead for an authentic 3D experience
It appears that 3D is the future of gaming, if recent developments are to be believed. The 3DS is incoming and Sony are pushing their 3DTVs left, right, center, center left, center right, and just in front of your nose. However, what's the point of a 3DTV if you have nothing to use it with? Therefore, Sony has been pushing 3D within their first party games, including Killzone 3 and Motorstorm: Apocalypse.
The latest game to enter the third dimension is Ratchet and Clank: All 4 One, a 4 player co-op title featuring everybody's 5th favorite pair of gaming mascots. How the game will work with 4 players gathered around the same screen is as yet unknown. I just hope that you have four pairs of 3D glasses or your least favorite child may have to go without. Poor little Timmy.
