Floods
When it rains, it pours. And as any Filipino will tell you, when it pours, then half of Manila becomes submerged in murky waters. That’s about the same in Death Stranding 2, as rivers will overflow and certain areas become nearly impossible due to flooding.
If you attempt to cross flooded rivers on foot, then you have to maintain your balance so you don’t get washed away. It’s either that, or you could easily stumble and lose your footing due to the current. Alternatively, if you’re driving a vehicle, then traversing flooded areas uses up more battery energy.
In any case, if you did bring a ladder or two, you can construct a makeshift bridge to get across rivers. Alternatively, you can use a PCC to build a bridge foundation, and then donate the necessary resources to its terminal. This creates a wider bridge made of concrete and metal, which vehicles should be able to cross without issues. These fixtures remain permanent in your game, too, until you decide to dismantle them. Players may also use them or they can help donate their own resources, too.
