Complete playthrough (all three mission packs). Wolfenstein 3D, but moreso, this standalone expansion follows much the same formula with few additions (one new enemy type is about all), but levels are typically much larger. While this might be seen as a positive in being more content, most are quite labyrinthine, to the point that it detracts from the experience - especially as mission pack 2 onwards features a lot of levels with mandatory routes hidden in 'secret' walls. With little indication of where these are - there's no graphical difference, just occasional aspects of the level design might suggest their presence - finding them becomes largely guesswork, which just isn't much fun. Regardless, the enjoyable core of the game is still present so, while there's little depth to the gameplay, Spear of Destiny is a decent enough experience all told.
