Omega: from past groups I've DM'd for I've notice this- you may not always have use/need for Jump Pack, but you always have use for a big gun.
Ollumhammersong: If you want to know more about Chapter Specific powers PM me and I'll look it up.

Everyone else: If you have started the Character Creation process AND have access to the Core materials...you may go ahead and finish spending your starting XP on Stats/Skills/Abilities/Powers ect. 

DO NOT: Roll for Past Event, Roll for Power Armour/History. Some of your RP may have an effect on this.
GEAR: Everyone starts as a Deathwatch Recruit. You are issued x1 Close Combat Knife, x1 Bolt Pistol, x1 Boltgun, Codex, Grey Deathwatch Jumpsuit, Chapter Trapping
