Chronicles of Riddick: Assault on Dark Athena. I can't say I enjoyed it much. I started it at hard difficulty and it was exercise in frustration. The enemies are incredibly quick, have amazing aim and each of their attacks hurts much more than yours. After they find you, they also always know where you are. When it got into shooting part, it turned into slug fest and I had to repeat every area many times.
After I killed 1st Alpha Male, who was very annoying and hard, I got bored with next enemies and lowered difficulty to normal.
The enemies suddenly became stupid and slow and the rest of game was incredibly easy. I think I died about 1 or 2 times to enemies (+ few times to environment). I went through all Athena endgame in 1 go. Alpha Males + boss, drone controling section and final boss.
So the game has no right difficulty for me. One was annoying and frustrating, other too easy. When there is mech sequence near the half of game, I had to reapeat it several times before I managed to get through and when I did it was really close call. There is very similar drone controlling sequence just before final boss and tehre enemy barely scratched me.
There was also quite a lot of bugs, the game is heavily scripted, tries to screw you at every opportunity, sometimes enemies reacted to my sneaking and I had no idea why and sometimes they ignored me when I jumped right in front of their faces and the ending felt abrupt, rushed and not too believeable.
I'd rate it
6.5/10.
Full list.
