I replayed the second iteration of Riddick games, "Assault on Dark Athena" and all I can say is it's pretty action-packed like the previous one. Still it's shorter. Again you're in the shoes of the meanest survivor there, Riddick and this time you have to escape from a mercenary ship after you have been adducted.
You have lots of side missions after getting off of this ship on a colony. You fall on this planet because you're taken down by this evil ship.
You have new guns like Ulaks and SCAR gun which are pretty useful.
The game is worth trying by every action fan .
