Total Annihilation
"Total Annihilation" was one of the first RTS games to feature radar that showed enemy units within its radius on the minimap. This added an additional element of electronic warfare to the game: players could construct radar jammers that prevented units in a small radius around them from appearing on radar. Mobile radar jammers could be used to create surprise attacks, necessitating the deployment of scout units on a regular basis to reveal said units visually. In addition, radar jammers could disguise the presence of visually cloaked units, such as the commander or land mines. Radar fields rendered cloaked units detectable; a radar jammer could make said units undetectable until the radar jammer was destroyed. "Total Annihilation" was also one of the first RTS games to point the way towards battlefields with hundreds and thousands of units. Previous games could field a hundred units or so. However, Total Annihilation initially permitted 250 units per side which was later patched to 500. A third party patch allowed up to 5,000 units per side.
Empires: Dawn of the Modern World
"Empires: Dawn of the Modern World" is a real-time strategy (RTS) game in which the player guides a civilization through five historical periods, from the Middle Ages to World War II. As in many RTS titles, the player collects natural resources, erects buildings, and trains and maintains a military. Players use a mouse cursor interface (or hotkeys) to direct their units, which range from crossbowmen to King Tiger tanks. A three-dimensional (3D) camera system allows the player to view the action from any perspective, including isometric and first-person angles. A mini-map is included as well.
