One of the most important things I've learned as a developer is to listen to the audience and after hearing a lot of complaints about this fight feeling unfair and frustrating to most players, it has been adjusted to be more friendly and fair to all players. So thanks to everyone who shares their feedback so we can make a better game together.
-The execution will only occur when you are very low on health and the range of this execution is decreased considerably.
-The speed of this enemy is decreased a bit.
-The time between attacks is increased.
-There is now a margin of error that allows you to dodge this execution.
Tips to beat this enemy:
-Since there is an automatic execution when you are low on health, always remember to heal up when starting this fight.
-You can parry his attacks, just use the shoot button without aiming a bit before he attacks you.
-Don't forget to dodge, watch her attack animation carefully, it's slow and allows you to dodge right when she starts.
And don't forget:
Aim for the head!
PS: Remember that you can now add to your wishlist my upcoming game that will serve as a prequel to Selene's story:
