This time around, G has more eyes that you’ll have to shoot to stun him. Once all the eyes have been popped, he will kneel, during this phase he will expose several eyes so shoot them until they pop. You’ll have to repeat this cycle a few times until he changes to a reddish color, here his attacks will be faster but the eyes on his chest will stay exposed so keep shooting at them until he dies.
You’ll need to keep a large distance from the boss in order to avoid his lunge attacks but beware he will pick up objects around the arena to throw at you so get into cover and use the opportunity to shoot the eye on his back. Make sure you explore the arena as there are lots of ammo, healing items, and grenades to use against G tucked away in the corners.

Boss: Super Tyrant
Finally, after of hours running from the Tyrant you’ll be able to go head to head with him but beware, you don’t have very much space to dodge his attacks.
To begin with you’ll have to watch out for his large arm because he will try to throw punches which can do some serious damage. Whilst dodging his punches you’ll have be ready to move out of the way of his swipe attacks where after each swipe he’ll get closer. In the middle of dodging the other attacks you’ll need to be prepared for a jump attack.
Now you know the Super Tyrant’s attacks, it’s time to deal some damage of your own. You’ll be able to see his heart exposed in the middle of the chest, shoot this with either the Shotgun or Lightning Hawk to deal some serious damage. After enough damage has been dealt, the Tyrant will become stunned, use this opportunity to deal even more damage until he becomes stunned for a second time. Eventually he will charge up a super attack where you’ll see the Tyrant’s arm covered in fire. This is the perfect opportunity to use the Lightning Hawk on his heart to stop his charge up. If you don’t deal enough damage, he will sprint with an attack that cannot be avoided.
Once you’ve prevented his super attack, you’ll need go back to shooting his heart, after you’ve stunned him a few more times a cutscene will trigger. Following the cutscene you’ll be able to pick up the Rocket Launcher but don’t collect it straight away as you’ll need to divert the Tyrant away from it first. Once the Tyrant is out of the way, head in to collect the rocket launcher and fire it at the Tyrant to finally kill him once and for all.
With the Tyrant defeated at long last, you’ll be able to escape the lab for good, exit the lift and head for the train to complete Leon’s story.
