The leapfrog: If you're stuck in a tight spot
                and running low on health, try leaping over
                the enemy facing you and getting the hell out
                of Dodge. This move works great in open
                areas, but it can be confusing and fatal when
                attempted in a small room.

                Jump 'n' shoot: Your RPG will try to target
                any living enemies, and here's a way to make
                the most of it. Hide behind a crate or other
                object; then jump in the air and fire a missile.
                If there's an enemy anywhere close to where
                you're pointing, the missile will hone in on it.
                Great for Dukematch slugfests.

                Strafe and turn: When using spiral
                stairways, slide in one direction and
                occasionally turn in the other direction to
                keep your weapon trained on the middle of
                the stairway. If you're going up a spiral
                staircase that turns right, you'd strafe left
                and tap the "turn right" button. You can also
                use this technique to circle an enemy, but if
                you have Run Mode on, you'll probably be
                moving too fast to keep a steady aim.
