Hello all
I have a couple of problems with SS4 and have found some
Easter Eggs that I have not found reported so far.

Problem 1 - Kleer
Starting when crossing bridge to reach Vatican. Kleer attack
and when I shoot them they do not die and disappear. They keep
moving around but with no character animation. They are also
treated as being killed. All Kleer act the same from this point
onward.

Problem 2 - Mechs
I ride a mech. I kill all enemies when attacked then as soon as
I move I am killed. The only way round this is to use God mode
and continue on foot.

Easter Eggs
On the level with the French resistance. The leader is called
Michelle - this is the name of the resistance leader in a
1980s UK TV sitcom called 'Allo 'Allo set in occupied France
during WW2.
When Michelle gives orders she says 'Listen very carefully, I
shall say this only once' - this is the phrase used by Michelle
when giving orders in the sitcom.
The painting recovered on this level is mentioned as being
painted by Van Klomp. One of the story arcs in the sitcom concerns
the painting of The Fallen Madonna with the Big Boobies by Van Klomp.
