Fire in the Lake (۲۰۱۴)

Volume IV in the Series: COIN (GMT) dives headlong into the momentous and complex battle for South Vietnam. A unique multi-faction treatment of the Vietnam War, Fire in the Lake will take players on US heliborne sweeps of the jungle and Communist infiltration of the South, and into inter-allied conferences, Saigon politics, interdiction of the Ho Chi Minh Trail, air defense of Northern infrastructure, graduated escalation, and media war.
Fire in the Lake features the same card-assisted counterinsurgency game system as GMT's Andean Abyss, Cuba Libre, and A Distant Plain, with twists that take the Series to another level, including:

Pivotal events that trump initiative (Tet Offensive, Vietnamization, Easter Offensive, and Linebacker II)
Inter-coup campaign effects that vary by RVN leader
Counterinsurgent guerrillas (US-led Irregulars and ARVN Rangers)
Insurgent troops (NVA) for direct force-on-force engagements
Tunneled VC and NVA bases
Trail construction and degradation
A larger-than-ever event deck for even greater play variety
Short and medium-length scenarios with either random or period-event options
