Over the last few weeks I have been playing a few games to test out the changes I made to my Grid-based SciFi rule set. They seem to be working for me with only one or two typos and cross referencing to tidy up.
Here is a battle in full flight with a space marine dreadnaught waiting to reinforcements as chaos marines advance. The lava pits are bomb craters filled with some railway model rocks I coloured red.
The last few play testing games used my Tyranid army (my favourite and first 40K army).
Now I just need to update the rules and read through them again in an attempt to minimise errors.
