Wow. Good thing controllers cost 60 bucks or mine would be sticking out of the drywall. This checkpoint system was clearly designed by someone who HATES GAMERS!
Case in point: The Bam Bam Club mission. You go in, you attck a few guys as the old geezer target runs off. No biggie. Then 2 other guys come out and you have to beat them, thats a checkpoint. Then you have to jump down to lower level and take out about SIX OTHER GUYS, bearing in mind that if you die at any point you get to start back at the checkpoint. If your good and can get the knife from the one guy no issue.
Then you go into the restroom and 4 other guys want to kill you....bear in mind....if/when you die you will have to go allllll the way back to just before you started fightning the 2 guys.
Broken save system. At this point I am just going around and getting all the health temple things (did the Amanda thing, got a perk that shows them on my minimap) so I can get my health maxed out.
