I used to run a 250+ person monthly LAN party, and without fail every single time we would be consumed by the 3-way action that is Giants.
While admittedly single player is a bit of a yawner, nothing will ever compare to having a standard multiplayer shooter shook up by the randomness of Kabuto.
When my friends and I saw this game here on GoG, we waxed nostalgic, bought a few copies, and 8 hours later we were still screaming our heads off when Kabuto snuck up behind us and ate our team.
Good times. Buy now.
