Your Construction Vehicles are not useless after your
base is built. When a fleet of enemies is at your base's door,
include the Construction Vehicles to meet them. They can help
eliminate Core or Arm Vermin if needed. Set a Construction Vehicle
to "Reclaim", then target an enemy. Your vehicle will
suck the life out of it, kill it, then add some metal to your
gauge.
Strategy: by Jarrod Hampton

Works only on Multiplayer or Skirmisk mode-
during gameplay, press enter and type +nowisee

Type [Asterisk]X at the opponent/ally selection screen. To specify another number of players substitute "X" with a roman numeral from 3 to 10. For example, [Asterisk]III will result in a three player skirmish

(arm v core). Here is a tip use the cheat
