WarCraft II: Tides of Darkness, developed by Blizzard Entertainment and released in December 1995 for DOS, arrived at a pivotal moment in the real-time strategy genre's history. Its predecessor, WarCraft: Orcs & Humans (1994), had established Blizzard as a serious contender in the PC strategy space, but the sequel expanded nearly every dimension of that foundation into something far more ambitious. DOS was still the dominant gaming platform in 1995, with Windows 95 having only just launched, and the game took full advantage of the hardware capabilities of the era — running in 640×480 SVGA resolution and pushing the limits of what DOS-based games could deliver visually and aurally.
The game places players in command of either the human Alliance or the orcish Horde across two separate campaigns, each comprising roughly twelve missions. The human campaign follows the defense and eventual counter-offensive of the kingdoms of Azeroth against the invading Horde, while the orcish campaign tells the same war from the opposing side. Each campaign introduces units and buildings gradually, teaching mechanics through escalating mission objectives rather than a formal tutorial. Missions range from straightforward base-building and resource-gathering exercises to tightly scripted scenarios with fixed unit rosters and time pressure.
Gameplay revolves around harvesting two resources — gold and lumber — to fund the construction of bases and the training of military units. Players click to select individual units or drag a selection box to group them, then right-click or use command buttons to issue orders. The tech tree is layered: players must construct specific buildings in sequence to unlock advanced units such as the Paladin or Death Knight, and researching upgrades at dedicated structures improves attack, armor, and special abilities. Naval and aerial combat, both absent from the original game, are central to WarCraft II. Sea battles involving destroyers, battleships, and submarines add a second strategic layer, and air units like the Gryphon Rider and Dragon can bypass ground defenses entirely, forcing players to maintain mixed-arms forces.
The single-player campaigns are accompanied by a map editor — the WarCraft II Map Editor — which shipped with the retail release and allowed players to construct custom scenarios. This was a notable inclusion for 1995 and contributed significantly to the game's longevity. Multiplayer was supported via IPX local-area networks, modem-to-modem connections, and null-modem serial cables, with Battle.net support added in the later WarCraft II: Battle.net Edition (1999). In its original 1995 DOS release, online play required third-party services such as Kali to route IPX traffic over the internet.
Upon release, WarCraft II was met with strong enthusiasm from the PC gaming press and players alike. It helped cement the real-time strategy genre as a mainstream category on PC and directly influenced the design of subsequent genre entries throughout the late 1990s. The game's production values — including fully voiced unit responses, a sweeping orchestral-style soundtrack by Glenn Stafford and Tracy W. Bush, and detailed sprite artwork — set a new benchmark for the genre on DOS hardware.
