"It's simple.
The images you click on (weapons, NPCs, wallpaper) are all shaded blue or red. LIke on red, you go ds.
To test this, you will see that the wallpaper choices don't switch like the rest do, just click on it, wait, click again, wait, repeat."
Yeah, that's simple. But what about the click "Sion + frenziedly click on anyone but T3 = DS" and "T3 + frenziedly click on anyone but Sion = LS" thing?
A subtle hint? A bug?
