Buckets and Water Bombs
Pick up and use Buckets and Water Bombs, they soak your opponents by doing as much "damage" in one hit as several shots from your squirt gun.
Dry Off
Just about fully soaked? Over time your character will start to dry off if you don't get hit, or to quickly recover just use a towel.
Radar
Use the radar to your advantage to see where your enemies are. Look for the blips on the radar to see them before they see you.
Choose Your Weapon Wisely
There are different kinds of water guns; some are for up close and personal and some are for distance. Some even do splash "damage", literally!
Stay Out of the Water
Running through water, such as fountains or the ocean, doesn't just slow you down; it also gets you soaked!
Watch Your Water Gauge
As you shoot your water gun you use up the water stored inside. Always keep your water gun filled or you're liable to be left high and dry when an enemy drops in!
