Overview
The purpose of this guide is to break down all of the various towers and their item upgrades in Defense Grid 2.

Tower item upgrades are passively added and do not require a Boost Tower below them, or need to be activated in any way. As soon as you build a tower, it will have the upgrade you chose before the level started.
How to get tower item upgrades
Currently being investigated.

Upgrades seem to be given randomly after winning a level, in single player, co-op or competitive multiplayer.

From dev Kaboom here
"Specific tower items are rewarded at random, so there is no set level or playthrough that will reward X item. However, there are things you can do to increase your chances of getting a higher quality item or just getting one in general. What map you're playing, what difficulty you're playing on, and how long you've been playing the mission are all factors in your chance of getting an item as well as its quality."

Tower Farming 101:

Play on "Practice, open, elite" with Practice mode you start with 2,500 resources and gain a ton more per tick. As such, gold rank is virtually guaranteed. So every match you have a very high chance of getting a card (even if it doesn't show, surprisingly).

Play missions 1-3 (not the tutorial mission 0) repeatedly, as they only have 20 waves, and you can farm cards really fast.

Hey, thanks for this list!
Anyone know how exactly work the "additional damage"? It only apply to the effect (eg fastest, strongest, stealth) or it is passively added to the tower?
How work the chemical bullets/shells and other dots? second hit (like if two Cannon hit same target) do stack another dot or just refresh the original?
Different DOTs like different source burning effect overwrite eachother or they eat enemy simultaneously? Like Inferno burn effect and Concussion Fire Bomb effect and Meteor Fire Ball or Plasmaball?
Thanks

Does "Bonus Versus Fastest" apply to the fastest alien in target range or only to aliens designated as "fast"?
Buzzsaw 2017 年 7 月 14 日 下午 3:51 
Vanon, have you done any stages on 'hard' setting? I was getting tower items for everything but the missile tower for a while until I did a 'hard' stage.
vvvvan 2017 年 1 月 22 日 上午 12:41 
Anyone else not getting any tower items (augmentations) for one tower? I have received absolutely nothing for Inferno after 30 hours (completed campaign, normal and easy, all gold). All of my other towers have tons of great items, but one has none. Weird. Also, effects one achievement. Seems like a bug or something. :steamsad:

Minor typo: Cannon Airburst Ordnance should say "unleashed", not "unleased".

Updated. thanks Chris
CH_Wolfe 2014 年 11 月 25 日 下午 7:31 
BTW, in addition to Meteor's Plasmaball 04 text being different, the other two I have say:
01: "Intense heat reduces the impact radius, but burns for an additional 30% damage over time."
02: "Intense heat reduces the impact radius, but burns for an additional 60% damage over time."
