Guns ‘n Grenades is a downloadable, tactical rule set for wargaming with 54mm plastic army men, retailing for $1 U.S. The rules are simple – only 11 pages in length, including numerous illustrations – but they make for a quick and cheap game.
The mechanics are easy enough; roll one six-sided die, add your attack or defense modifier (depending on what your troops are doing), and compare it with your opponent’s score. If the attack roll is higher than the defense roll, a hit is scored.
Soldiers each have four stages of life in this game: healthy, wounded, bloodied, and dead. When a soldier is hit, he usually loses one stage. The authors recommend using slips of paper to identify wounded or bloodied targets.
Plastic soldiers are divided into types, based upon the way they are sculpted. For example, a figure holding an assault rifle is a common rifleman, while any figure aiming down the sights of his weapon is considered a sniper. The authors even found a use for that officer-style pose with the pointing arm – they are scouts. There is a total of nine soldier types.
Some soldier types also have tags, or terms that describe special abilities, a mechanic similar to the special rules function in Song of Blades and Heroes by Ganesha Games. These tags denote certain rule exceptions or modifications for a specific unit. For example, deadly units inflict wounds costing two life stages on a successful attack; light units enjoy a movement bonus.
The game also includes basic rules for vehicles, including tanks, armored trucks, and light artillery, which is towed about the field by the trucks.
