I think I will be using my figures for two different eras ;
The first will be a modern Zombie game using mainly British vehicles like the Astin Martin , Mini and Landrover models I already own . I will be using mainly Zombies and Foundry/Hasslefree figures. the setting will be the UK.
The second will be a Futuristic setting about 2040 using the big Trucks and maybe some Hover Tanks and such from Old Crow . I will be using Zombies and anything suitable for the Era minus the British vehicles mentioned above . The setting will be a destroyed European City.
I think I'm happy now , thanks for everybodies help.
