description: "All commanders have twice the armor and speed, and six times the building power. This makes the commander a much more central unit, rather than having it become mostly obsolete after the early game. The increased usefulness means that playing \"Game Continues\" is no longer an invitation to bomb the commander. Strength lite is ÜberComm Lite: half again the armor and speed, and three times the building power, for the same reason. This package replaces ÜberComm and PowerComm, both by Immerman. The strength choice is the only difference between those two originals."

description: "Commanders have half again the armor, build three times as fast and reach twice as far. Arm commanders move seven times as fast, and Core commanders five times as fast.\n\nSuper Commander (Arm) and Super Commander (Core), by MAC (macraig), both promise 50% more armor, 500% more speed, 300% faster construction and 200% more build distance, so the commander stays useful after the early game. The two copies do not use the same speed numbers. Arm multiplies top speed by 7 and braking and acceleration by 49. Core multiplies top speed by 5 and braking and acceleration by 25. Both multiply damage by 1.5, from 1 to 29900, build distance by 2, worker time by 3 and turn rate by 5, up to 29900. This version keeps each side's numbers. The idea is Immerman's."

description: "Start from a gate and teleport in the commander you choose.\n\nArm starts with the Normal gate and Core with the Easy gate, which makes 40 energy and 3 metal and stores 3000 energy and 1000 metal. With a chosen arrival, Arm's gate is the Target gate: attack-order the ground and the commander is built there. Core's gate is the Random gate, which picks the spot. When the battle room says Game ends, losing the gate ends your game. Some computer profiles may not use the gate. If the match does not start on a gate, that profile is the likely cause. With a chosen arrival, a computer player on Arm's side never gets a commander: the Target gate builds only where a player attack-orders. On Core's side the Random gate works for a computer.\n\nCommander arrives: at-gate puts the commander on the gate, as Warp Gate 3.1 did, and the gate is itself a commander. near puts the commander near the gate, as 4.0 and 4.1 did, and the gate's script places the build point 8 to 30 units out. near-twin gives two commanders, as TwinComm did. chosen builds the commander where you choose, as Targetting did. chosen-twin gives two commanders, at a chosen spot or a random one, as TwinTarget did.\n\nThis package replaces * Warp Gate 3.1 *, * Warp Gate 4.0 *, * Warp Gate 4.0, Targetting *, * Warp Gate 4.0, TwinComm *, * Warp Gate 4.0, TwinTarget * and * Warp Gate 4.1 *, all by Immerman. It follows 4.1. One package holds the six versions, the sides keep their names and prefixes, TwinTarget's two commanders may both exist, and the battle-room screens, their art and the instruction plate are left out."
