Houdini Research Tip

  • 1 of 4: If you got some good photos of the houdini splicer you met in the Tea Garden, you should be able to run up to this houdini splicer and photograph him to get the second-level houdini splicer research bonus.
  • 2 of 4: It's a physical tonic called Natural Camouflage, and having it equipped will make you invisible every time you stand still (and are not using any weapons).
  • 3 of 4: The constant noise associated with fading in and out of visibility can get annoying, but this tonic is well worth having equipped. Even splicers who are right next to you can't see you if you're invisible! (Until you move or attack them, that is.)
  • 4 of 4: Note that you usually can't hide from enemies who've already seen you and started attacking you, even if you run out of their sight and stand still.
