Swim Bug 3

This shows four examples of the swim corner bug at the Sacred Lake. It works at all corners that point northeast and no others. Place lara facing the wall so that when her hand extends she barely reaches the corner. Turn a bit less than 45 degrees and dive. Press Swim once, then turn a little more from the wall. Repeat until she enters the wall, then tap Forward to move her in until the bug jumps her to the top.
