PC’s, on the whole, can be an unpredictable lot, suddenly going off in completely the opposite direction to that which you (the DM) had planned, or insisting on visiting a possible adventure area that appears on their campaign map - but which you have not designed yet. This is where a ‘side-track’ adventure may be able to help. The basic idea behind these ‘mini-adventure’ supplements is that, while they can be used a small adventures on their own, they can also be ‘inserted’ into an existing adventure or campaign as an extra area for your players to explore.
Each ‘side-track’ adventure therefore concentrates solely on the ‘dungeon’ aspect of the encounter(s), and contains full colour floor-plans for use with your 25-30mm miniatures (if you so desire). Even if you don’t use miniatures, using the floorplans to show the layout of the dungeon is a great time saver (rather than having to quote the exact room dimensions for the party’s mapper all the time).
With any luck, these ‘side-track’ adventures may help you create a more believable world for your players to explore - after all, it’s always a good idea to have a back-up dungeon or two up your sleeve for those times when your players seem to ignore every hint you throw at them and go off at a complete tangent.
