Am I the only one that found Dead Space 2 Hardcore really not that bad? yes it got annoying but hard would be the word I would not use. But if I had to pick my hardest game I would say GT5 "vettel can suck it" and CoD W@W.. Also I have not played Frontline on PS3 but I owned it on PS2 did they make it harder because I don't recall it being as hard as people are making it seem. "could be because I beat it like 450 times".
Outside the dream world, life can be harsh, even cruel, but it is life.
For me it used to be W@W on Veteran, with the grenade spamming and enemies 2 shot killing you.. till Dead Space 2 came along. Without buying the DLC which gives you better suites and weapons from the get-go, Hardcore mode with 3 saves is hard! Just look at the percentage of gamers that have achieved it, 16%.... BOOM!
COD : W@W & Dead Space 2 were definitely hard. But I would say SPEC OPS : The Line FUBAR mode is even tougher. Try it and make your own mind up, but that shit is NO JOKE. Admittedly a fraction of that has to do with the controls being a little wonky, but none the less, it's ridiculously difficult and not because of grenade spamming which is the main reason W@W was so tough. Still, as hard as that is, I've never seen anything that comes close to Vanquish's God Hard Mode. There's a reason it's called that. You have to be a God to complete it. Same with the Challenges in that game. Namely Challenge 6. Never seen anything so difficult in a videogame in my life!!!
