So I'm playing Oddworld : Stranger's Wrath...  I'm in the middle of a mission:

    I've already bagged a handful of guards without being detected.  My ammo is full, my health is full and I have a plan of attack to draw out the guards from inside the facility.

 "All I have to do is hide until they drop their guard, then I pick them off one at a time as they leave the base."  I spy what looks like a garden of tall black, suspiciously rusty plants.  "These should be perfect cover!" I thought, "But why are they spattered with blood?...oh well."  Being the cautious soul that I am, I dive right in...to my grisly death.  NOT plants...sharp jagged rusty (and obviously efficient) perimeter defenses.  Lesson learned.
