Heyya folks,

I've got a digital project which involves Space Marines, Orks, and most likely Tyranids. I may be considered really new at this and there's so much awesome backstory to go along with this universe...

Let me ask the experts.. What are three major 40K battles that involve these three races at one time? The races may not have to actually fight, but be involved somehow.

Any help and breadcrumbs to follow up on would be such a great help.

Thanks in advance!! You guys rock!
