hi.
I have updated oc_sso.
A present version of oc_sso is v0k.
The 4th area can be played in this version.
A new boss also added it.
Some screenshots is here.

In area 4, underground ruins are stages.

There is a building like the temple, too.

The boss in area 4 is a fight on the elevator that is descending in the tunnel.
The boss is huge gunship.

The boss does various attacks.
It is possible to fight against LastBoss by defeating the boss in area 4.
Last Boss is Gman 00

The expression of the Meteor strike changed with oc_crimson.

If a constant amount is damaged, gman becomes a berserker mode.

Gman attacks it with the sword in addition to a usual attack.
