Today, SCEJA (Sony Computer Entertainment Japan and Asia) released a bit of information on the main weapon in the Freedom Wars game; your “thorn”.
The thorn is a long vine-type lasso with embedded thorns, and can be used either for movement or attack. Several players using their thorns at the same time can tie down an abductor (the massive bio-weapon enemies you face in the game) in order to help bring it down.
Check out the screens, though apparently only the one is large sized (wtf, Sony?);
Looks interesting from what I can see, though I think I need to give it a go before I decide 😉
Freedom Wars is scheduled to release in Japan next year; no word on a Western release window yet.
