Here is some battle report we did at Overlords Club in London few weeks ago.
We have played 2×2 game with 1000 pts each. Imperial fists and Crimson Fists against bugish horde of Tyranids. I had my Gastos Rhor Librarian, 5 Terminators, 3 Centurions with grav-cannons, 5 tacticals with plasma, Land Raider and Land Speeder Storm with scouts and heavy bolters. Quite lucky with this game: initiative seized, rolled with good Orbital Bombardment warlord trait from Sentinels of Terra list.
