How to Write Your Own Bolt Action Scenarios!

no comments

Writer of Bolt Action, Alessio, show us all what it takes to create your own Bolt Action scenario!
Alessio: This article is a set of guidelines about writing scenarios for Bolt Action. This advice has been derived from my own personal experience of writing many many scenarios for different purposes within the Bolt Action game system over the years.

From that experience I have to say that there is a huge difference between writing balanced ‘battle scenarios’ and more uneven ‘historical’ scenarios. The first are aimed at being playable in competitive events like tournaments, with both players having equal chances of winning. The latter are more for fun and aimed at capturing the flavour of a particular historical engagement or campaign/sector of the war. And they are, in my opinion, very different beasts!

As the historical ones are those that are far more commonly designed by players all over the world, this article will concentrate on them. Players that are interested in ‘balanced’ tournament scenarios are more normally happy to use the ones in the rulebook, or simply tweak them to adapt them to their needs and likes.

So, when you have just read about a particular engagement or theatre of WWII, sometimes the inspiration might take you – “You know what? This battle would make a fantastic scenario for Bolt Action!”
I know it’s certainly happened to me in many occasions, and maybe if I take one such moment as an example, I can then talk you through how to turn that instant of inspiration into a playable scenario.

I will use as an example this anecdote I read about in a book about the siege of Leningrad. Apparently there were moments in winter when the Soviet Baltic fleet was frozen in at their base of Krondstat near Leningrad. These ships were being used to augment the Russian artillery firing out of the beleaguered city against the enemy positions, but at the peak of winter the harbour and nearby sea water froze, which gave a chance to German and then Finnish troops to attack the naval base over the ice. In particular I loved the account of night raids by Finnish special forces, which would ski over the frozen ice carrying grappling hooks and then effectively attempt boarding actions against the ships to hopefully damage or destroy them or their main guns. Finnish elite troops scaling huge battleships frozen in ice and fighting at close quarters against Russian ‘Black Death’ sailors… you must admit it would make for a very funky scenario (and an even funkier wargame table!)!

Let’s go through the various components of a scenario:


When designing a scenario that you wish to share with someone else, start with a brief description of the events (like the paragraph above!), and then add a few evocative, and relevant, pictures. A few pictures can really create the atmosphere for the game. These work for our example.

OK, I’ll admit that the last one is a bit of a joke.


Then it comes to inform the players about what forces they should use for the scenario. Of course if you are so lucky that you have a detailed order of battle for an engagement, then you can base it literally on those and adapt it to the reinforced platoon (or armoured platoon) selector system of Bolt Action. You can either use the generic selector, or instead (more appropriately in the case of these historical scenarios), use an existing theatre selector for the sector where the engagement is set and use that as is, or modify it as needed.

To continue our example, I would state that the Finnish player must take a force chosen from the Finland Attacks selector in the Armies of Italy and the Axis book, but cannot include any vehicle or artillery, and that all infantry must be Veteran where possible and cannot include normal infantry squads nor Allied squads (basically meaning it’s going to be made of the most elite infantry available to the Finnish list).

The Soviet defenders instead will be picked from the Leningrad Approaches selector in the Armies of the Soviet Union book, and similarly to their opponents the Russians cannot have vehicles, can only have anti-aircraft artillery, representing the ship crew manning the smallest calibre naval AA guns and turning them onto the attackers. Their infantry squads must be composed exclusively of Naval infantry.

After telling players what selectors to chose their forces from, you must also tell them whether both forces will have the same number of points (say 500, or a 1,000 pts a side), or whether this is going to be an uneven fight, where one side has more troops than the other (say 20 to 50% fewer points). If this is the case, the disparity in forces must of course be compensated by some other advantage, either one or more special rules favouring the smaller side, or a tactical/terrain advantage in their favour. They could for example have a number of minefields, obstacles, buildings or even bunkers to deploy within, or the larger side might begin with only a portion (half?) of the forces and get the rest as reserves…

And don’t worry too much over balance. Keep in mind that historical scenarios are rarely going to be balanced in terms of both sides having an equal chance of winning. And that’s fine. Only very rarely in real war it happens that both sides have roughly equal forces in a particular area. You can be simply interested in doing better than your historical counterparts, or you can choose to play the game twice, swapping sides, and see which player does better with the weaker force. This last option actually means that the two sides have once again fairly similar chances over the two games.

Said this, try at least to make sure that the scenario works and there is no ‘automatic victory option on Turn 2’ for one side to execute. “Hey look, all of my units escaped by moving up this road and exiting the table straight away!”.

In our scenario, you could go for equal forces, assuming that the naval forces are mostly been deployed inland and are not manning the ships. Alternatively, you could go for a larger defending Soviet force, but make the Soviets turn up from reserves (e.g. coming up from the barracks in the base to the frozen-in ships).

Remember, the Soviets should get some defensive positions, but the Finns could get the advantage of surprise (maybe a penalty in Turn 1 for ordering all Soviet units?).

Set-up & Terrain

This is all about clarity – you need to give clear instructions about who sets up what, when and where. It certainly helps if you provide players with a map, which should show the recommended terrain for the table (see next header) and ideally also highlight the set-up zones, with clear labelling or captioning of distances and other instructions.

A map makes the set-up instructions so much easier, both for you to write and for players to then understand them correctly!

It is important to spell clearly the following points:

  • in which order do the players set-up?
  • How many or even which specific units can/must start the game already on the board.
  • How many or which units can/must form the first wave, coming in automatically on Turn 1.
  • How many or which units can/must be left in reserve.
  • Whether special set-up rules (snipers, observers, spotters…) apply.


Coming before or after the Set-up instructions (depending on which one makes it clearer), this header instructs the players about terrain placement and density. You can be very specific and restrictive about this, telling players exactly what terrain they are going to need and where to place it. In some scenarios this approach is fine, and it has the advantage of being very clear. However, do keep in mind that you cannot make assumption about the quantity of terrain available to players. You really cannot expect most people to be able to place on the table, for example, a 25mm-scale battleship frozen in ice…

So, when you do present very specific instructions, always follow them up with a paragraph that tells players how to replace the requested terrain in an easy to represent way. For example, you could draw the top-down view of a battleship on coloured paper and lay that down on the table…

It is easier to write terrain requirements in a more generic fashion for scenarios where the exact layout of the battlefield does not matter as much. In those cases, you can be more or less specific, from a simple “cover about 25% of the playing surface with wooded terrain” to a slightly more precise: “try to match the terrain layout presented in the map, but do keep in mind that Player A is going to need a bunker in his set-up area for the scenario to work”.


This is very simple – just tell both players what are their aims for the game and how to win. This header is not vital and can also be subsumed into the Victory! header below.

Game Duration

Once again, nothing complicated here, just be precise. For example, the game can end in any of the following situations (or a combination of some):

  • when a player concede or is wiped out.
  • After a fixed number of turns.
  • When a particular victory condition is achieved (the battleship is blown to pieces!).
  • Random game length (my favourite!). In this case, after a number of turns, players start rolling on pre-determined schedule and the game will end on the roll of x, y, or z. For example, at the end of turn 6 roll a dice, on a 4+ play turn 7, then game ends. Alternatively it can continue – at the end of turn 7 roll a die on a 3+ the game ends, or play Turn 8. The value required can change faster, slower or not at all…


In connection with the game objective, tell players how Victory is calculated.

This could be a simple all-or-nothing condition (e.g. either the ship, bridge, artillery position, etc. is blown or it isn’t).

In other cases, it could be a far more nuanced calculation. For example, players could receive a number of ‘victory points’ based on eliminating enemy units and/or getting their units on one or more objectives. Choosing to only use positional victory points values makes for a very different game than choosing to only using victory points based on casualties. In one game, the lives of your men are very expendable; in the other they are not so much! Mixing both is always quite interesting, as players must gauge how many casualties they are prepared in order to achieve strategic advantages, which in my opinion feels more realistic.

If you do use victory points, remember to clarify whether units are simply worth a point each (which is easy to work out in the end). Or a different amount of points, like for example their own requisition points values (i.e. a sniper team is around 50pts, and a Tiger tank is around 600…). This might require a calculator at the end of the game, but it feels more balanced, and is used in most tournaments. If you mix this system with objectives, remember to state how many points each objective is worth. For example, blowing up a main turret on the ship is worth 200 pts, while blowing up the ship’s magazine, and therefore the entire vessel, is worth 500, or even automatic victory!

The last thing to remember when using points is to clarify whether a victory by a single point still counts as a victory, or if one player must have a certain margin over the opponent for the game to count as a win rather than a draw. For example, a game might end with 1,238pts versus 1,104pts or 7pts versus 6pts – is that a victory or a draw? Tell them how much margin they win to call it a victory – I tend to go for at least 20% of the value of the forces in play if you use requisition points, or a margin of at least two points more than the opponent if you use normal points.

Special Rules

Finally, I think that a few special rules are funky and can give a lot of flavour to a scenario. And within the safe confines of the scenario, you have far more freedom to create characterful rules, which are probably not very balanced and would break the system if used as a normal game rule!

In our example, you could add rules for assaulting a defended position using grappling hooks, a rule that can be re-used by someone designing the Rangers’ assault on Pointe du Hoc…

Also, you can throw in the mix some commonly used special rules, like limited visibility, minefields, weather etc, to be found in the BA rulebook’s appendices.

One word of warning though – do not go overboard with special rules, as you might end up with something that does not play like BA anymore! Or indeed with something that is utterly utterly unplayable as your brain has to cope with a million exceptions to the normal rules you are used to.

So, keep it brief, keep it simple and once again, don’t take this too seriously – this is game, and remember that it is supposed to be light-hearted fun!


P.S: Why don’t you send in your scenarios and if they are good enough we might publish them here! Oh, and if someone builds that ‘assault on the frozen-in battleship’ please let me know, as I’d love to get involved! (with rules, not with modelling, trust me, you don’t want me to help you with modelling, painting, or anything else that involves hand-eye coordination!).
