Warcry have shot-up their review of Quake 4, here's a splatter from it:
"I will forever hold the railgun from Quake 2 in the highest esteem. Sound, heft, power. It was awesome. It seems very much like Raven looked back to all the previous versions of Quake and picked the arsenal they liked the most. All are well designed, have good sound effects and are a lot of fun to use, but most seemed slightly underpowered. I was used to my railgun turning most anything into a fountain of crimson gibs, but alas, it now takes several hits to liquefy a foe. Throughout the game, you'll get the odd permanent powerup here and there that modifies a weapon's damage or bestows a secondary firing mode upon it. Pretty cool."
