It introduces a new map under production.
oc_sso is COOP map of a stage clear type.
There is a boss in each stage, and when the boss is defeated, the
stage is clear.
It becomes a combat with the last boss if it clears by four stages.
Some screenshot is here.

The brush base weapons were made to be able to be bought by handling the merchant.
New brush base weapons are added.


This is "LaserSpread" of weapon newly added.
Five lasers are postponed while drawing tracks.
It is possible to attack it by penetrating through the obstacle.

This is boss "Ichthyo rider" in stage 1.
The player who is going down the river on a raft is pursued.
It attacks it by the laser while swimming in surroundings of the raft.

The vigorous attack is begun jumping onto the raft at a constant
cycle.
Ichthyo rider is attacked by the blitz and a bite.
I up-loaded the version that was able to play stage 1 of this map.
I am confirming it has some problems.
I plan to put out the improvement version in a few days.
