Uprising - Toy location: Just before the sniper valley where you drive a ghost, climb up onto the ledge to your right and use Sputnik + plasma grenade to grenade jump up onto the upper cliff. Head straight forward and you'll see a valley below you with a sniper Jackal on the far side on a ledge. Kill him from here, then follow the ledge around to the right until you can drop down onto the lower ledge that said sniper Jackal was on. Head down to where he was, and jump up onto the ledge to your right. Now head forward until the sniper valley you would normally progress through is below and to your left. Keeping this valley visible to your left, follow the left edge on this upper area until you pass a curved lower ledge and another lower ledge begins in front of you. Drop down to this ledge and head along it to the right (keeping sniper valley visible to your left once again) until it opens up into a wider area with a dead end and the toy by the wall in front of you. Description here is very tricky so check the video at 16:11
for this one.
