Space Pilgrim Episode III: Delta Pavonis contains a total of 7 Steam achievements, 3 of which are missable, the remaining 4 being story related with one being earned at the end of the Prologue and each of the three "Acts". Time to 100% is approximately 2.5 hours, although this can be done much faster if using a guide and skipping dialogue.

The only other significant point of note is that for me at least, there were no in-game Steam overlay achievement popups. The achievements are earned when their respective requirements are met, they don't all pop when you exit the game like some, there is just no in game notification.

A quick tip before we begin, to make the game run full screen, hold down the "Left Alt" button and tap "Enter".
