Shogo used to be my favourite video game on the PC platform. Weapons are really fun to use, the gameplay is so well-paced you don't have the time to get bored. Through the campaign you get to control a mecha which allows you to smash tiny soldiers into buildings in a feast of much more blood than the human body can hold. Then when you're not, you become the tiny soldier which may have to fight against a giant mecha. I also remember this game having great soundtracks, and also that unforgettable intro sung by a Japanese singer.
