How Undermine Works
I made this little scenario to teach people exactly how undermine works. Apparently it's changed since the start of AoM in a couple of ways — I knew it did less damage to TCs, but on top of that there is a limit to how much total damage can be done by undermine.
How the Scenario Works
It's pretty simple. I've set towers up everywhere and lighthouses so that you can see the whole map. I also put a few berry bushes on the map to show you where you should put your cursor to get the desired results.
On the left side of the map you'll see two rows of towers/berries:
- Top row: Simply click undermine where the berry bush is and observe how many towers it kills.
- Bottom row: Do the same thing. Undermine is always moving so long as it's not killing something, so the more towers there are, the less distance it can actually travel. You'll see the test with only towers at both ends is about 2 towers further than the other one. This test also shows you the width that undermine actually works under — you should see all 5 towers drop on the bottom test.
In the middle of the map I also set up another area where there are a tonne of towers. This one shows that there is a limit to how much damage can be done during undermine, which is approximately 6050 damage (11 towers killed at 550 HP each). It likewise shows you how wide the path of undermine is.
Try undermine a few times — you'll see that the green dots don't do anything as far as aiming the god power is concerned. Just fire away and it should work every time.
Tower Upgrades
I also set up two triggers which give tower upgrades to the second player. These triggers are not active by default. If you wish to turn them on:
- Go to the scenario editor
- Go to the triggers area
- Make trigger 1 and 2 active (or 2 and 3 — you'll be able to figure it out)
After putting both triggers on, you'll see even less towers get destroyed because the maximum damage dealt is reached a lot earlier.
Installation
Copy the uploaded file to your scenario folder, which is located in the same place as your savegame folder:
C:\Documents and Settings\[username]\My Games\AoM\Scenario
Then go to single player mode, click on "Load Scenario", find this scenario in your list and play away.
Notes
I didn't actually explain the exact mechanics of how undermine works or how to aim it, but by playing around with the scenario and following my suggestions you should be able to figure it out. I've found that just explaining it in text doesn't get the message through to most people, as it's not an easy thing to explain without a bunch of drawings.
