PvP (Player versus Player) Defense:
Key Structures: Their are 3 key base structures you need to protect, the Con Yard (construction yard), D-Fac (defense facility), Command Center (Importance in order from left to right). Try to place these key structures in the back of your base and behind the most covered part of your base forcing the enemy to go through more buildings to get to your Con Yard.
Lock Down: The last thing you want is to have all you defense lured away while leaving your Con Yard exposed. So place walls, turrets or cannons on the outside of your units to lock them in place. This tactic will force you enemy to go through all you defenses to get to the Con Yard.
Provide Protection: The enemy is going to send units who are meant to kill each type of your defensive unit. So to prevent this place unit to cover the key units you need to defend your base. Example : to protect your Anti Vehicle Cannon, place Anti air in front of it, with anti vehicle on each side on the Anti Air Unit, with Turrets on outsides of the Anti Vehicle units. this provide coverage of every type, to protect the key defense structure.
Know Your Units: Each unit has range, know this well. Use units with far ranges to provide cover or to hit slowed units. Example : Turrets will overlap a tanks protecting the tank from infantry, or Anti-vehicle Cannon place just right can hit enemy tanks as soon as they drive over anti tank barriers.
Focus Fire: Enough Defensive fire will kill any unit regardless the type. Try to set-up your defenses so that you can get a large amount of your units to be able to focus fire on a unit.
Repair Time: Regardless of your defense enough attack will destroy anyone, but you can make them really work for it, try to keep you D-Fac at least 4 levels higher than your highest defense unit. This will keep your repairs after every attack very high, forcing your enemy to enlist help or give up.
Combine some or most of these tactics and you will a force they player will think twice about attacking.
As we all know, losing your base is a very costly and annoying exercise. It also loses the alliance POI. Needless to say it is very important that we avoid this as much as possible. This means building a strong defence. Here is a short guide to building an impregnable defense.
Im primarily a Nod player so i'm no expert in GDI defenses. However, generally a good defense should follow a general order of:
1st row: anti-vehicle and anti-air. For nod this should be black hands and missile squads. For GDI, predators and pitbulls.
2nd row: anti-troop. MGs.
3rd row: Same as 1st row. Use flak turrets and missile towers in this row if you want to research them (which is up to you, you can get by without them).
4th row: whatever you want, but at least one MG.
Final row: anti-air. Mass missile squads come highly recommended.
Units to avoid:
-Any unit that does not fight back. Although walls are useful for stopping your defense from going after decoys. MG's also do this and are a better use of your defense points. Walls can absorb bombers ammo, but I think you are better off destroying the bomber instead. I have also found anti tank barriers and barbed wire to be pretty ineffective.
-Nod attack bikes. Too easy to destroy. Missile troops are much better.
- GDI guardian. I dont play GDI, but they seem pretty useless.
It is very important not to neglect your defense. Constant vigilance!! Do not think that just because you are surrounded by allies you can become complacent. We can handle an attack that we see coming, it’s the one we don’t see that we should worry about. You should have a defense that is strong enough to comfortably handle your own army at all times.
PvP Offense:
Here are some basic but very useful tactics to use when attacking and defending in PvP battles.
Attacking -
1.) Distract and Destroy :
If your enemy has many mobile units and no walls or turrets to lock them in place, Send the troops to the open side of the field while sending Bombers up the side with the Construction Yard. This will lure all defense units away from your bombers giving them a clear path to the Construction Yard.
2.) Blitz :
If the defense is locked down and it seem you can punch pass their Anti Air units, try to line all your Bombers in one wave next to each other, this force the enemy Anti Air to spread their fire giving you Bombers a better chance of getting pass the defensive line.
3.) Disarm :
If an enemy is actively on and is counter attacking you, Focus your fire on their Command Center. Most player will leave this building exposed to better defend the Con Yard, and D-Fac. Destroying this building with make you enemy unable to attack you, leaving him wide open to attacks, and you will not have to fear a counter attack.
4.) Flood :
If the enemy has a lot of walls and cannons, these structure will slow your units advance and will throw your timing off. So for walls send a few structure busters with your attacking unit to destroy walls and keep your units moving together, and flak cannons are destoyed very easily, a pred tank will kill an equal lvl flak cannon in approx 10 secs.
5.) Focus Fire :
Send units ina mix formation to throw off the defensing units, Example : a wave of "Guardian, Paladin, infantry, Zone Troopers, Orca, Predator".
Wave attracts all type of defense, but will focus fire on the defenders.
6.) Lure :
Your enemy alot our Anti Air but it is all in the back, but they need to be destroyed for you to get the Con Yard. So send a Air Unit on the far side of the Anti Air, and place anti infantry or anti vehicle ground units next to air unit. The Air unit will lure the Anti Air over and your Ground Forces will destroy the Anti Air, leaving the Con Yard exposed.
Combine any of these tactics to increase your odds of destroying a Enemy Base.
