Ooh, ooh! I got another idea! A game mode called "Chrono War":
All players start out with small base equipped with a Chronosphere, some power plants, an Ore Refinery, and a Barracks (but no Construction Yard). The goal of the game mode is to destroy the other players' Chronosphere.
However, a twist: the Chronosphere here has some abilities unique to this game mode. Along with the standard Chronoshift superweapon, it also has several other Chrono-related powers:
1: Chronoshift Reinforcements (Tier 1) - Teleports in a random selection of 9 Tier 1 vehicles, ships, or aircraft. Since the selection is random, a big element of risk is present.
2: Chronoshift Reinforcements (Tier 2) - Teleports in a random selection of 9 Tier 2 vehicles. Same as above, but more advanced vehicles.
3: Chronoshift Reinforcements (Tier 3) - Teleports in a random selection of 9 Tier 3 vehicles. Same as above, but the most advanced vehicles available.
4: Backwarp: The Allied Tech Center repair ability. Self-explanatory.
5: Neutron Blast: Erases units in an area of 9 cells from existence.
6: Chrono Elites: Teleports in a random selection of 9 Chrono-related infantry (Chrono Legionnaires, Cryo Commando, Chrono Ivan, Chrono Adept, or Siegfried).
7: Chrono Vortex: Not a true support power, but a side-effect of Chronosphere overuse - literal paradoxes start spawning randomly around the map, usually around areas where Chronosphere support powers are most used. May result in the following: Units being teleported randomly across the map, units being erased from existence, units being replaced by another unit, units changing sides, neutral hostile units from alternate universes appearing, units simply being killed, random dangerous weather patterns, and dinosaurs. Yes, dinosaurs.
All-in-all, a game mode that is absolutely fucking crazy. But hot damn, does it sound fun!
