And he will keep spawning in front of you
In other rooms with inf enemies
In Greece's beginning of XXL1 it also happens for a certain camera angle and position
The game spawns them in a different location so you don't see them spawn
I guess the devs simply didn't intend you to go to their spawn point, where in other cases you could be anywhere and they had to give them multiple options.
Especially since this roman has a stationnary behavior
and his guarding a tiny area
Another interesting thing
You know in Venetia the four torches
Room with Crash Bandicoot and Donkey Kong
The 3 Romans in the back next to the fragile squares
If you go to Obelix's "Launch pad"
They will follow you upstairs
I will get footage for those curiosities tomorrow
My run ended with this time
