You dont like waiting long hours with game open in background to get achievement?
Here i offer solution.

Here i will put link to my save file around last 30 minutes needed waiting (better than 15 hours after story done right?).

Here example of path where you put my file.
C:\Program Files (x86)\Steam\userdata\ your ID\543870\remote

You replace STORM2.S file but save your original somewhere before doing any funny stuff with your folders.

(small bonus... if you open items you should get i love ninja tools achievment too because i collected them all not sure if it works but for try you dont give nothing.)

Here is your link:
