The Martian infantry formations smash the ‘Thin Red Line’ with minimum of casualties and the Brits withdraw.
In my version of the Space 1889 rules, the Oenotrian shield guns are multi barrelled and at close range are fatal against unarmoured troops. A design they developed from their own technology after seeing human multi guns.
Though expensive they are cheaper than human rifles and most importantly (apart from the useful close quarters punch) they are not reliant on humans for supply.
These results bare out over half a dozen test games which we are happy with.It gives back some balance to the Martian forces against mass manufactured rifles, machine guns and more effective artillery from the armies of the ‘Great Powers’.
