Space Hulk Missions.... 'The Return of the Argo'

[arcadianlegion]

I have created my first Space Hulk Mission.... I feel like a proud father, even if it's crap I'll still love it! So 'Lost and Damned', if you have the time to try it out please do and let me know what works/ doesn't work etc...
I've played it twice and the Space Marines have been wiped out both times... where am I going wrong?
Its in the 'downloads' section of my Space Hulk Solo site.http://www.wix.com/JohnWheldon/Space-Hulk-Solo

[MortiS-the-Lost]

Me and Mark RG are going to give this mission a go some time soon, we'll let you know what happens
