1) Beat the game on the hardest difficulty, which includes a hundred dollar charge per continue. no money, no more game. You have to reload at your last checkpoint.
2) Not spend any money at a Dollar Bill machine. While this may not seem like a big deal, health, ammo, and salts (Which is basically your mana) are at a serious premium in 1999 mode, and these machines are basically the only easy source, outside of hoping to...
Thats really cool man, I hope you keep hitting strides you enjoy. I envy this kind of dedication myself and hope that I can find a game that warrants me putting this kind of love into its harder aspects. I am playing through(post will come) Legend of Zelda: Link to the Past right now and playing through it entirely by memory I accumulated a few decades ago is a kind of achievement I am pretty proud of. Scoured every area of that game and it still comes to me.
Are there any things left for you to achieve with BioShock Infinite?
I have good and bad feelings about achievements. I like a good mix of stuff you're going to do anyway, to chart your progress, and fun stuff to do. I was really annoyed with finishing up Fallout: New Vegas and having some achievements left that consisted of doing a certain amount of damage with weapons I didn't care about.
I mean I did them anyway because with Bethesda games I'm a hardcore completionist. I created a hard save and then went to the strip and blew up securitrons. But it didn't add any extra challenge, just busy work.
Now I just have fun and do a little mopping up. Voxophones, infusions, and drunk killing. .
