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 nothing 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.
