Bulletstorm

"* "Once you've picked up a weapon for the first time, you can unlock upgrades and such from drop-pods. Some upgrades aren't immediately available, so don't forget to check back on each weapon's screen every once in a while.

- If an enemy can't be kicked or leashed because they're too fast, you can shoot them to stagger them, and THEN kick or leash them.

- No enemy, as far as I'm aware, is too fast to dodge a sliding kick, so use that liberally.

- Certain combos are good for points because they're easy to pull off. Slide into an enemy and shoot them in the head with the shotgun for an easy 50 points.
