Well since I decided to play vindictus again, I noticed that they have Vindictus for steam now. There is also an event item you get for using steam.
I figured out how to transfer your existing vindictus files onto steam.
What you need to do is go to your steam folder
C:\Program Files (x86)\Steam\steamapps\common
Code:
1. Create a folder and rename it "vindictus" (without the quotes).
2. Next go to where your Nexon folder is and find the vindictus folder.
C:\Nexon\Vindictus
3. Copy the en-US folder
4. Paste into the new steam vindictus folder.
C:\Program Files (x86)\Steam\steamapps\common\vindictus
5. Open up steam and go to the steam store.
6. Search "Vindictus" in the steam store.
7. Click "Play Game"
8. It should bring up a pop-up window that asks you to install, just hit "Next" 2 times.
NOTE: At this point it should say something about Discovering Existing Files. If it doesn't you did something wrong.
9. Have patience for a couple minutes. Download should be really short now (I only had to download 4MB).
10. Play Vindictus!
11. Profit.
