I met my friend Vincent for a quick 500 point game of 40k last night.
He brought Imperial Guard. He had a Demolisher, Chimera, Command Squad and two units of Vets with special weapons.
I brought a basic Overlord, 2x 5 man Warriors, Annihilation Barge, 6 Scarab bases and 2 Spyders.
The Scarabs were brutal. They stripped 11 points of armor from the Demolisher on turn 2. Also, the Spyders just kept making more. I ended the game with 9 bases! I think I gained 8 bases over the course of the game. That's an extra 120 points worth! I might have to get a 3rd Spyder.
