I actually like this. The challenges in SP adds replay value to the game. Not like the game isn't worth playing through again anyway. I just beat it and I have to say I like this game more than I thought. Definitely going to try and get this!
Easy enough. As the name implies, you can just grind each challenge on a checkpoint by reloading it. Each challenge can be tracked through the main menu under "Grinds" in the Story/Multiplayer sections. Golden guns also tie into about half the challenges, so it's imperative that you hunt down the collectables as you play.
Most of the challenges have different degrees and magnitudes as you complete them, getting more tedious as you ascend from bronze to gold rank challenges.
sooooooooooooooooooooooooooooooooooooooooo close, just got the lounger grind complete , now just shotguns, melees, people falling, 8 more bullet cams and im done! wow, the time spent on this one alone.
Double damage is easy to grind on chapter III checkpoint 8. You'll kill about 13 goons including the last two on stairs. Then just reload checkpoint. Similar story with shotgun dues. Load the same checkpoint, get the shotgun dropped by the guy down the stairs, get some ammo on the way, go upstairs killing two guys there, through the door. You'll start another checkpoint. Switch to shotgun. You'll get about 10 kills with it and just keep reloading that checkpoint from now on.
Dude ^^^ it says finish ALLLLLLLLLLLLL GRINDSSSSS what does all mean to you? Your asking if bronze is fine. Obviously no. Get plat for each one. So each grind says "COMPLETED" Why do people make achievements harder to understand? I don't get it
Chapter 10 last checkpoint is a good spot to get platinum medals in shooting enemy projectiles (start the checkpoint and stay in the cover but don't kill anyone and they will take turns trowing grenades at you), destroying cars there is about 6 cars which you can shot at which also gets you the killing enemy's with explosions medal
Chapter 5, checkpoint 13 (I think) for projectiles bro. There's one molotov every 5 seconds as opposed to half minute. The end of Chapter 10 is good for vehicle destruction and killing enemies in explosions.
Currently grinding Chapter 8, checkpoint 5 for Dodge Brawl (Shootdodge kills)
#32 - Don't rush to stand up after shootdodging, just stay there on the floor and pick off any enemies you can. You can also just lay down and shoot everyone until you complete it. I got this one just playing through so it's not a difficult grind.
~36 I can't rmember the chapter but it's the level in the bus terminal at the point where you shoot a gantry that two enemies are running across. They fall and die. That checkpoint reloads at the exact moment you rush to shoot it so this is quite a lot quicker to complete than you'd think
For Blow Out, I think Ch. 13 Checkpoint 5 might be the best one to get kills with explosives. Just use the grenade launcher where the LAW is on the left side (after you find cover for the first time), and grind some kills after you take out the vehicle.
If you know anywhere else that can grind this one faster than the place I mentioned, that'd be great.
after 4 play throughs the only ones i needed were melee kills, grenades shot out of the air, vehicles destroyed and blind fire kills. melees finished in about 5 minutes on chapter 6 2nd to last checkpoint and the other 3 about 20 minutes chapter 10 last checkpoint
