Quick guide on HOW TO DELETE GAME SAVE FILES so you can restart from scratch.

WARNING : It will reset everything, meaning you'll lose every loot/marines/RP/etc...

DW* = DeathWatch enhanced edition.

For some reason it is impossible for a few people to delete from the common steam/steamapps/common/DWenhanced/etc...

I managed to make it work like that :
1) Right click on DW on steam and go to properties and turn off the cloud.
2) Press windows+R and search " %appdata% ".
3) You should be on the ROAMING folder. Go one folder back to APPDATA. Click on LOCAL.
4) DEATHWATCHGAME -> SAVED -> SAVE GAME.
5) Delete everything in this folder.

It should work.
If it does not, then chaos gods are making a clown from you.
Seriously, it is the only way I found to delete saves since going from steam files does not work.

Hope it was useful.
For the Emperor !
