How to unlock the Tower Expert achievement in Defense Grid 2 - Definitive Guide
Edit: Changed guide to match my updated guide for the above achievement.
I did this on the first level (denoted by 01, not the tutorial) on Normal by playing on the Fully Loaded setting. You should be able to get it on Easy.
Block the top left and bottom right road with a Boost tower and put a third Boost tower on that square in between these 2. I put a Cannon on the middle boost, an Inferno on the top left, and a Gun on the bottom right. Focus on getting these completely upgraded, then put a different boost upgrade on each of the 3 Boost towers. After that, I don't think it particularly matters where you put the rest. Just try to place them logically (IE an AOE tower like the Concussion at the first curve, and the long range towers near the core). I had enough resources to fully upgrade everything after wave 19.
As with all other achievements in this game, the achievement won't unlock until you beat the level.
I have included a video below with a guide if you need more help.
There are a total of 9 different defense towers and each can be upgraded twice. To obtain this trophy, you need to have built every kind of tower and have at least one of every kind fully upgraded (it’ll turn red after the last upgrade). Note that in the earlier missions, not all towers will be unlocked yet, unless you’re playing in the ‘Fully Loaded’ mode.
This trophy is cumulative so it doesn’t need to be done in one mission. Since there is a trophy that actually does require you to do this in a single mission, you can save yourself some time by doing this in conjunction with the Full House trophy.
If you start out playing Story mode games, this achievement cannot be unlocked until you reach Split Decision (Chapter 7) as that is when the Missile tower first becomes available. However, as soon as you beat Chapter 1 you can replay it in a non-Story mode and choose Fully Loaded, enabling you to unlock this as quickly as your second mission if you so desire.
There are 10 tower types and you will need to build at least one of each and then fully upgrade them to level 3 to unlock this achievement. You can keep them or sell them without impacting the achievement, and they do not all need to exist at the same time. The 10 tower types available are:
- Boost (no upgrades available)
- Gun
- Inferno
- Laser
- Cannon
- Temporal
- Concussion
- Meteor
- Missile
- Tesla
The achievement will unlock at the end of the mission in which you upgrade your final tower type to level 3, win or lose.
