: Position your defenders (or turrets) so they have overlapping fields of fire. In RimWorld , building a walled-off base with a single open entrance creates a natural kill zone.
: A good Killzone should look like a "busy inner city" from above. You need enough large pieces to block line-of-sight and smaller pieces for cover.
In games like RimWorld , 7 Days to Die , or tower defense titles, a Kill Zone is a designed bottleneck where enemies are funneled to be destroyed efficiently.
