General information
The Defense Simulator is a building that allows you to test your defenses. For its building statistics see Combat Buildings Stats. By succeeding in a Simulator attack you can win Stars, Simulator Boosts, Parts to enhance your Defense Buildings, and Incendiary Cores.
"Test your base defenses and earn XP with our new Tower Defense Mode! Build the new Defense Simulator and battle waves of Marines, Pulse Tanks, Bombas and more! Complete all the campaigns to show that your base is the best."
Campaign Selection
The Campaign Selector
Build the Defense Simulator on your base and through it you can embark on a number of defensive campaigns against stronger and stronger NPCs of differing levels, research levels, and troop compositions. More campaigns will unlock as you level up your Defense Simulator building.
Each campaign has a number of individual attacks that can be initiated by using a charge of the Defense Simulator, which is similar to that of a Warp Gate, except that it has a shorter recharge time of only 15 minutes and a 6-launch capacity.
At the end of each simulation you will be scored as to how effectively you defended your base receiving XP and an item. Any buildings lost in the simulation will not be damaged when you return to your base.
The key to maximizing the points is to lose no buildings in the fight (3 stars) and do it on the first attempt (2x bonus). The key to winning in the first attempt is to either blow a simulator charge to see where that particular level will attack, or to know beforehand. See Campaign Info for more details. By defending with your strongest towers at the point of attack you can defeat a simulation for the maximum score. Eventually, of course, you will meet enemies too strong for your level.
Boost Selection
Defense Simulator - Boost Selection
After choosing the campaign, you can apply both a XP boost and a defense boost, from those available on the Boost Selection screen.
Level Images
Stats
- ◊As of 01/09/2012 (probably earlier) the Defense Simulator is built if you start a new player.
- *Levels 10 and above require 1x Cerulean Core to upgrade.
Boosts and bonus
As you can see in the following sections, the maximum boost you can receive is 240, if you use a Defense Sim XP x30, lose no buildings and are unlocking the simulation.
XP Boost
Depending on what you choose on the Boost Selection screen, battle XP is multiplied by:
- 1x (no boost)
- 2x (Defense Sim XP x2)
- 15x (Defense Sim XP x15)
- 30x (Defense Sim XP x30)
Star XP Boost
Depending on the number of Defense Buildings you lose in the simulation, you will get stars and XP boosts as following:
- No buildings lost*: 3 stars and 4x XP boost
- Less than 1/2 of total turrets lost: 2 stars and 2x XP boost
- More than 1/2 or total turrets lost: 1 star and no XP boost
- Note: non-defense buildings such as barracks/factories may be lost without incurring in any penalty. Only losing a turret will prevent you from gaining 3 stars.
Unlock bonus XP Boost
The first you win a simulation you will get a 2x XP boost.
Attacks come from which direction?
Polar directions
On the mission selector you have 8 possible choices.
The first page of Defense Training starts at N and end at SW. The second page of Defense Training starts at S and end at NE. And so on.
| N | NW | W | SW |
| S | SE | E | NE |
| N | NW | W | SW |
And it continues around your base counter clockwise.
This means that when the last mission of Tank Maneuver is in W the first of The Vanguard missions will be SW.
Note: some campaigns DO NOT follow the counter-clockwise scheme, with attacks coming from seemingly random directions (Noted in All or Nothing, other campaigns may have this feature/bug).
Note: some simulations with multiple kinds of unit may not attack from the same spot. Some Ahh! Giant Spiders' simulations have this feature, but it's mostly noted in All or Nothing (and probably onward). For example, Shrikes may appear from the S corner, and after a few seconds Disruptors and Pulse Tanks will spawn from the N corner, usually far away from the base, out from base's visible boundaries.
