Sandbags can be very useful, but also be a fairly serious threat to both sides, depending on placement. My suggestions.
- Add in a way to make a variant of the sandbag wall that has a small “V” cut out of the top, that way, players can shoot through while still having protection from the sides. They still count towards sandbag limit.
- Allow sandbag walls to be stacked 2 tall. When looking above an existing sandbag wall, the outline will snap to it, allowing for taller walls and windowed barricades to be built.
- The bottom sandbag cannot be deconstructed unless the top one is broken first. This also would make it harder for enemies to break down window barricades from awkward angles. It can still be broken with explosives, just not deconstructed.
Since the limit is still 10 walls, building taller walls means using more of the limit. This results in larger defenses up front and hopefully less cases of teammates blocking ALL entrances, cutting their team off.
