Then I strengthened the body with coffee stirrers (not my first choice but it was what I could find). Looks a bit odd now but will be unnoticeable when it's painted. The bed was left a little uneven so I thought I should put a bed on them. The plan is to use it as a terrain feature so an even surface for figures to climb on was important. More coffee stirrers and a bit of green stuff and here we are. All it will need is a bit of a finish on the greenstuff when it dries to smooth it off. If there are anymore gaps, the primer will hopefully sort them out.
Most immediately this is for the X-Com game. That said, this vehicle should do fine in anything modern or near future, especially zombie related.
