Serious Sam 2

• In Serious Sam 2, you are stripped of your weapons very often. If you have a decent-sized arsenal, expect it to be removed in a level or two.

• The Minigun makes the Uzi completely obsolete when you get it.

• Secrets aren't as useful as they are in the original Serious Sam, as they consist mostly of treasure items that increase your score. Score means jack-shit in this game, so feel free to ignore them.

• Don't forget to use your hand grenades to soften up enemies or thin out hordes of Kamikazes/Clowns.

• You can get up to 200 health and armor via regular health/armor pickups. Take advantage of this.

• Use your Chainsaw to break open crates instead of wasting ammo on them.

• The Double Shotgun will probably be your most-used weapon throughout the game, as it is usually found early on, and does great damage at everything except extreme long range.

• Don't forget to charge up your Cannon and Grenade Launcher.
