Force 4X consists of three six-Blockman robot sets that correspond to the Japanese C-1X releases: Force 40 for C-11, Force 41 for C-12, and Force 42 for C-13. Each set included an instruction booklet, as well as a sticker sheet that was identical to the Japanese release (complete with C-1X-coded stickers for the cockpits). Force 4X was identical to the original 1984 Japanese C-1X sets. The chrome pilots were moulded from yellow plastic underneath the chrome finish.
No giftset collecting the Force 4X sets was released in the Robotech Robolinks line, and the Force 4X combination ideas on the back of the boxes do not include the super-robot mode emphasised by the C-4X giftset in Japan. The stock photography on the front of the Force 42 box promote the Force 42 super-robot mode, but use the larger retractable super-robot face intended for when all three Force 4X sets are combined into one super-robot, as in the C-11-12-13 giftset.
