I played my first game of Planetstrike last weekend. I was the attacker with a Daemon Army and my friend Shaun deployed his IG and three Bastions as the defenders. Both armies were around 2,000 points.
I started with the Firestorm and rolled nine attacks. We agreed that Guard units targetted could take cover in their lines. Ducking and covering gave them a 2+ save so few were killed but most units were 'gone to ground'.
All the daemons can deep-strike by definition so the bulk of my army arrived on turn one in the midst of the defenses and could assault straight from deep strike (Planet Strike rule). We agreed a house rule that the Guard would still get the 2+ save on the first turn of combat but that only delayed matters a little. By the end of turn three the Guard were mincemeet and it was all over.
The Bations Interceptor guns had little impact on the game, performing better as normal guns.
The Planet Strike Rules combine to make a daemon attacker damn near unstoppable; there was nothing Shaun could do.
One could remove the firestorm from daemons as that would leave the defender up and shooting on turn one.
Anyone else played a game yet?
