Boss 5: Proto Tyrant - second encounter | Boss battles Resident Evil Zero HD Guide

The second encounter with the monster takes place when you explore the Treatment Plant. More specifically, it happens after you use the small lift and before you find the motherboard required for solving one of the riddles in the game. This time both playable characters can participate in the battle.

The beginning of the second encounter with Proto Tyrant

The second encounter with Proto Tyrant doesn't differ much from the first one. The monster has same abilities as before and his strong attack with the upper limbs remains most dangerous - it can knock your character down and take large number of health points. The battle area is slightly larger this time, but you don't have to run through the whole room - just keep your distance.

Try to especially protect Rebecca from boss' strong attacks

The greatest handicap in this battle is the fact that the boss can be attacked both by Rebecca and Billy at once. It is a good idea to control Billy and position yourself so that you cover weaker Rebecca - this will minimize the chance for her to receive damage. The characters should use grenade launcher and Magnum to attack the boss, this will allow them to defeat him even faster.
