1 - When using Trinity Nuclear Launcher attack, show a circle for the AoE that it will hit, so we can place the attack command with more precision, same for missiles from Missile Silo. In case of Trinity also auto map mark hit/AoE circle for team to see and not team-kill, after auto erase map mark after some seconds.
2 - When build Singularity Reactor or Geothermal Generator (normal/advanced) show a circle for explosion/death radius, like missile silo show missiles attack radius. This will make easier for newbies stop building one right next to another...
