Mushroom Men: The Spore Wars' freaky arsenal this week with two categories of weapons: thrusting weapons and Radical! Weapons. The idea of a thrusting weapon is fairly simple to understand: it's a pointy thing of some kind on a stick, and your mushroom uses it to poke at stuff.
Radical! Weapons are special weapons that have limited ammunition and are used at certain specific points in a level to obscure a hole in the wall or otherwise destroy an area that is the source of repeated enemy spawns. They're slightly more sadistic and demented than the normal weapons. And by "sadistic and demented" we mean "a flamethrower made from a match, a whistle, an aspirator, and a football bobblehead."
