Sometimes when you restart the mission it mixes up your goals. Half the time it will just say to kill the Javalena with a pistol and the other half it will tell you to use the blind. Make sure you are following which one it says to do and you will be fine.

this is false, because if you press select, it will tell you your goal, and it still doesnt work. I've shot one from within 40 yds, and i failed! i've used the ground blind, and i failed, repeatedly! i've tried without a scope,....and failed! there has to be a glitch in the game or somthing cause its happened on other levels too

you do not have to do that mission, you could play the hunt on that level and unlock the
nexy mission

I think the mission is glitched up cause i shot the javelina from a ground blind many
times and it always says i have failed so dont worry about it.
