Expansion for Popular Front: Escalation expands the base game by adding 54 cards and a new power for each faction, encouraging players to develop unique strategies for each of the six factions. It also introduces new retreat and naval combat rules that increase the strategic depth of the combat system. The stakes of each turn's political resolution have also been increased, as the next turn's turn order is based on this resolution.
Each faction is given 2 unique card types (3 and 2 of each) and there are some new generic cards, common throughout the decks. This results in a bit more card counting, but not an insurmountable amount. The available tactical ploys are greatly increased from the base game. The strategic depth of play is increased as well.
