Know How to Fight Your Enemies
You have control over two capable fighters in Resident Evil 0. This means that it might be a better idea to shoot and kill all the zombies in sight. It’s already hard enough to dodge attacks as it is, and with two people, the chances of someone getting caught in a nasty zombie embrace will be higher. Instead to taking a blow to your health level, it might be safer to clear out a room of regular zombies instead of running past them.
The leech men are a new enemy type in Resident Evil 0, and they may seem terrifying at first, especially since your bullets don’t deal as much damage to them. The trick to fighting them is to use fire. If you have a grenade launcher and some flame rounds, these leech men will go down pretty quick. I also recommend using molotovs against them.
