Complete the three campaigns on the Hard difficulty to unlock this achievement, unlocking this achievement will also unlock the “Tempus Fugit”
achievement.Online/Offline Tips:Special Abilities:
Make use of your Special Abilities, especially the ones that allow you to bomb an area of the map without risking any of your forces. In many cases the structures that you attack will not be repaired by your enemy and with a few volley of the Ability you can destroy Bonus Objective, or enemy defenses, or other useful targets.
Special Abilities like the Soviet Magnetic Satellite can be used to decimate very powerful enemy attack forces that would have been costly to defend against.Base Defenses:
Many times whilst playing on Hard you will be outnumbered and will need large attack forces to cause any damage to your enemies. Because of this it is often wise to build up strong base defenses and let the enemy blunt their attacks against your walls and defense structures without costing you anything more than the cost of repairing the damaged buildings. This will also mean your own forces don’t suffer many (if any) losses.Abusive Tactics:
Some maps that seem difficult can be abused by using certain strategies. For instance your enemy may have multiple bases and be weakly defended from air attacks, if this is the case send in a small group of air units to breach this gap and cause as much damage as possible. An attack on a large group of Power Plants can cripple the enemy’s defenses, making a previously fortified position easy to destroy.Expansion:
Don’t underestimate the usefulness of having more than one base, being able to build more Ore Refineries, launch raids from different locations; extra places to repair units are just some of the benefits provided by expanding your bases. The extra income will also mean you are able to replace lost armies faster, build up defenses faster and make you all round harder to defeat.Offline Only Tips:Saving:
Make sure to save before and after every successful attack or defense, and load your game if anything goes wrong for you.
Make use of the 9 save slots you have available, as it is sometimes useful to go back to earlier points in the mission.AI Coordination:
Co-ordinate attacks with your AI co-commander, although the AI co-commander is nowhere near the usefulness of a human co-commander it can be used to distract the enemy, or split the enemy’s forces during a joint attack. It is often worthwhile to support your co-commander when they are attempting an attack, especially if they are committing heavily to the attack.Sacrifice Your Ally:
In some games it may become clear that your co-commander is nothing but dead weight and isn’t helping you at all. If this is the case let them get destroyed by your enemies. You could even help by using the force attack command (RB+AA).
This will mean your resources are now yours alone.Note:
There are a few missions where specific units must be kept alive; if one of these units is under your allies control make sure they stay alive.Online Only Tips:Human Coordination:
Having another human player in the game can make things much easier even on the highest difficulty. Make sure to co-ordinate your attacks. Attack a strong enemy position from two sides, so the enemy must split their forces. Or overwhelm your enemies with sheer numbers.
