Fortress S

Severe balancing problems with extreme difficulty spikes.
One boss early game seemed broken due to forced unavoidable damage. After 3 hours of attempts it was only able to be beaten through an exploit found on a Japanese forum.

Progressing through the difficult story mode is mandatory to unlock local multiplayer and other game modes.

Game has two campaigns turn based, and action based. Local Multiplayer does not seem to support turn based option.

The games English localization is terrible.

Playthrough was aborted on level 9 out of 21, due to another difficulty spike/broken boss.

There is no searchable content at all for assistance such as walkthroughs, guides, tips.
It is recommended to avoid this release.
