I am sure that many of you are dreaming about what it will be like as an astartes once deathwatch comes out. Fortunately, Fantasy Flight games released the stats of a space marine in purge the unclean. Basically, as I recall, this guy would have been able to clean out an entire space hulk of warp beasts and Dark Eldar without working up a sweat, the acloyte team was just being baby sat by him. What can we infer so far about being an Astartes?...
1/ 2X toughness, making the toughness bonus 8 (maybe 10 in some cases)
2/ Astartes Armour would be 10, 11, and 12 for the head, limbs and torso respectively. I wonder what terminator armour will be like but I am guessing AP of 15 or 16 in the torso (much like Mega Nob armour)
3/ Any guess of the damage output of a bolter, or a heavy bolter... or a chainsword... or any other heavy weapon handled by a devistator squad? If I recall, the guy in the book above had a thunderhammer which had a +17 damage bonus.
4/ Probably an amazing resistance to disease, fatigue, mind control, etc.
5/ Any other thoughts?
