This is a small addon that unlocks checkpoints for every difficulty, as well as gives you the two new weapons right at the start. Of course, free saving is still there on difficulties outside of Hardcore.

INSTALLATION:

Place DeusEx.u in GMDX/System and 01_NYC_UNATCOIsland.dx in GMDX/Maps. When asked to overwrite, say yes.

This addon can be freely modified and used as long as credit is given to me.

This addon was not made and is not supported by Eidos Interactive or Ion Storm.
