[H2] Description

Game Overview

Infernal Machine: Dawn of Submarine Warfare is a solitaire board game that casts the player in the role of inventor/entrepreneur in mid -19th century America. The game is set during a historical moment when the business environment has gotten rather dynamic – it is the tumultuous landscape of the American Civil War. The player’s task is to design, build, and put to use a submarine during that war.

Components that you’ll find in the game box.

Infernal Machine can be played either in scenario form or campaign. In a campaign, you can choose the city or port where the project’s machine shop will be located. Since construction materials and labor costs money, your role as entrepreneur comes into play as you seek out Investors to join your team; their cash will provide the funds that help your Fishboat take shape. As Inventor, your design gives form and substance to the size and shape of your submarine, and to its capabilities. Will it carry a snorkel? Will its prow have a spar-mounted torpedo as the primary weapon?? Will it tow a captive mine instead? Will it have dive planes? Will it be powered by the muscle strength of a crew cranking the propeller or will you install a boiler engine?

From the Scenarios Booklet, a pre-built “H.L. Hunley” showing completed construction and crew position assignments.

To bring blueprints to life, you will need to hire Mechanics, whose engineering expertise keeps your infernal machine’s construction on schedule. Once assembly is complete, your Mechanics can join the crew, using their repair capability to keep the machinery and the vessel running smoothly. Journeymen can also lend a hand on the shop floor and inside the Fishboat, while Sailors bring nautical know-how as well as sheer brawn.

While your machine shop is busy getting started with the submarine’s construction, the game reminds you that the war drags on, and it is an unstable business environment. Prices for materials and labor fluctuate. Current events can affect your construction schedule and your machine shop’s performance. Public, and even personal circumstances may force your hand. You may decide to push your Fishboat into the water before you feel it is optimal, or push your crew into battle with little training. So many decisions. Where do you turn and how do you find out what you need to know?

Fortunately, in this game the rules and player aids are designed to give the player’s question a direction to its answer, done through insertion of a clever Rule book and Cyclopedia page notation within the text and the player aids, quickly directing you to the correct answer being sought. This simple tool helps you to garner valuable experience, enabling you to learn the game quickly and accurately.

1 Hour and 34 Minute Video Interview and Discussion of The Guerrilla Generation and "COIN Beyond COIN" with Stephen Rangazas and Fred Serval
Interview from The Players' Aid with Stephen Rangazas

[H2] Description
For many Central Americans who came of age between the 1960s and 1980s, the solution to mass poverty, discrimination, and social exclusion lay in taking up arms against the entrenched structures of authoritarian militarism and oligarchic elites.

- Dirk Kruijt, Guerrillas

Some rebel groups abuse noncombatant populations, while others exhibit restraint, discipline, and control. Insurgent leaders in some countries transform local structures of governance, engaging civilians in the process of affecting political change; others build administrative machineries that do nothing more than extract resources. In some context, rebel groups kill their victims selectively; while in others violence appears indiscriminate, even random. Movements sometimes loot and destroy the property of civilian populations, while at other times they protect it from government attacks.

- Jeremy Weinstein, Inside Rebellion

The Guerrilla Generation: Cold War Insurgencies in Latin America is the second COIN multipack, containing four separate games exploring a series of thematically related insurgencies. Building on the The British Way, this new multipack allows players to explore variations in insurgent groups’ organizational structures, strategies, and relationship with civilians, across four insurgencies in Central and South America between 1968 and 1992. During this part of the Cold War era, Latin America experienced an incredible number of different insurgent groups, many inspired by the Cuban Revolution featured in Cuba Libre, ranging from popular backed rural insurgencies, flexible urban guerrillas, externally sponsored raiders, and brutal ideologically rigid groups. This multipack features a game exemplifying each of these types of insurgencies, to offer players the chance to compare different approaches to rebellion highlighted in the quote by scholar Jeremy Weinstein above. The Guerrilla Generation also offers four longer and more complex individual games than those found in The British Way, as well as an entirely different approach to the linked campaign scenario, which combines two games into a simultaneous side-by-side experience.

Highlights:

Four full games in one box: Explore four different conflicts set during the height of Cold War Latin America between 1968 and 1992. Each game uses a unique ruleset building on the same general mechanical structure, ensuring that they are easy to pick up while still offering a distinctive experience.
An extension of the COIN multipack approach with a higher level of complexity than the games in The British Way, introducing new changes to the core system.
Unique mechanisms reflecting the different attributes of each insurgency: exposing atrocities with Radio Venceremos in El Salvador, managing US Aid in Nicaragua, the hunt for Guzmán in Peru, and kidnapping officials to the People’s Prison in Uruguay.
Small board footprint with quick-but-deep gameplay: Each game plays in under 2 hours and takes place on a single 17” x 22” board.
A “Resisting Reagan” Campaign: A linked campaign scenario allowing up to 4 players to play El Salvador and Nicaragua side-by-side, with new mechanisms to represent the Central American peace and solidarity movement’s efforts to resist the Reagan Administration’s aid to both the Salvadoran government and the Contra insurgency, by influencing Congress and American public opinion.

El Salvador
The Salvadoran Civil War (1979-1992) was an intense struggle between an American backed government and an insurgent group that many label the strongest in modern Latin American history, the Farabundo Martí National Liberation Front (FMLN). Despite being a coalition of five different insurgent groups, the FMLN managed to launch two major offensives taking the fight to the capital San Salvador, develop a widespread support base in the countryside, and utilize sophisticated means to garner international sympathy while condemning atrocities by the government. The Guerrilla Generation: El Salvador borrows existing COIN series mechanics such as Pivotal Events while introducing new mechanics to capture the FMLN’s innovative tactics and the struggle within the Salvadoran government between reformist and rightist factions. Although more complex than The British Way: Malaya, the El Salvador game will also offer new players an introduction to the COIN series, giving them some familiarity with Government and Insurgent factions in other modern COIN volumes.

Nicaragua
The Contra war in Nicaragua (1979-1990) offers a completely different style of insurgency than the FMLN in El Salvador. The Contra insurgents heavily depended on external support from the United States to wage their war of attrition against the newly formed Sandinista regime. Operating largely from sanctuaries in the bordering countries of Honduras and Costa Rica, the Contra player, with the help of the Reagan Administration, aims to inflict increasing amounts of economic cost to the Sandinistas, conducting Sabotage to generate Unrest rather than build Opposition and battling the Sandinista’s forces directly. Much of the Contra’s attacks focused on civilian targets and risked driving the effected civilians to assist the Sandinista counterinsurgency efforts. The Sandinista’s counterinsurgency effort relies on mobility and firepower to eliminate Contras in Nicaragua and possibly even risk launching limited incursions against Contra bases located in neighboring countries. The Contra player must also manage efforts to maintain US aid for their war effort and may need the Reagan Administration to risk engaging in workarounds of Congressional limits that could lead to a scandal similar to the historical Iran-Contra affair. Nicaragua may also be paired with El Salvador in the “Resisting Reagan” campaign scenario that offers additional mechanics to model the debate over aid in the United States.

Uruguay
In addition to the two insurgencies in Central America, The Guerrilla Generation also offers two games on insurgencies in South America to include additional types of insurgencies and illustrate the tensions of waging counterinsurgency in democracies. The Tupamaros insurgency in Uruguay (1968-1972) presents players with one of the most famous urban insurgencies in history. Operating largely out of the capital city of Montevideo, The Guerrilla Generation: Uruguay adapts the COIN series to an almost entirely urban setting with all of the accompanying features such as safe houses, intelligence gathering, specific locations in the city, and additional headline events on every card to capture the chaotic nature of the capital in the late 1960s. The Tupamaros player must choose the organizational structure of their clandestine group, either a tightly controlled smaller group or an expanded group with command-and-control issues, each with its accompanying tradeoffs. Uruguay had been a successful democracy before the severe economic troubles and insurgency of the 1960s, and the Government player must balance the choice of undermining the democracy by expanding the role of the military in the conflict, which might allow them to crush the insurgency but risks a coup that topples the democratic government.

Peru
The tensions of counterinsurgency in democracy continue in The Guerrilla Generation: Peru, which covers the main period of the Shining Path insurgency (1980-1992). Peru transitioned to a democracy from military rule in 1980, making the new civilian government reluctant to entirely hand the war over to the military. Instead, the civilian government progressively placed more of the country under “emergency zones” that granted the m
