Wonder what will the laboratory do? :o EDIT: Nevermind, just got told by XmmmX19, I’ll keep it a secret though. ^ \_ ^

At the moment we are not able to reproduce this bug. Do you remember what upgrades you used?

What upgrades do ? I don’t see a “help” button

don’t understand what the factory do. each time i raise the level, nothing seems to change at all EDIT: never mind i found out

I updated the FAQ! :D > *Originally posted by **[alexmanya007](/forums/32139/topics/613234?page=1#posts-10293078):*** > > What upgrades do ? I don’t see a “help” button You can find out by hovering over the upgrade name with your mouse.

Hey, what all do you lose when prestiging up a tier with HQ? Curious so I don’t waste resources on upgrades I’ll lose anyway (like factory stuff, level 3 elements, etc). EDIT: Nevermind, made it to Tier 1 myself and found out. So for the benefit of everyone who hasn’t made it there yet: You keep your Factory and Laboratory as they are, with all upgrades you’ve already purchased. (So max out those upgrades while the resources are flowing.) You lose all unspent special resources and blueprint points, and also your max levels, total damage, and max upgrades (clicks). Your start bonus is reset to reflect this, although it will still be enhanced by any techs you’ve researched.

How do you get blueprints?

And how do you upgrade the factory production amount? Problem solved. I missed it on the factory screen.

How do you get additional blueprints? How do you unlock insane? I dont see these explained in game.

Insane is unlocked when you tier up in the command center, blueprints are the blue bricks you get either by spending special resources in the lab, or through the factory. The biggest piece to getting to tier 1 (insane) is reaching lvl 400 in hard mode.

How do you get to the town?

what does the colors mean? I don’t understand most of it I only get red = fire, blue = water, green = nature and black = darkness and white = normal? what is the color of universal? air? and etc… no guide for it…

Hi, I can’t see information about upgrades anymore by hovering over the text, is there a way to fix that or….

how does aura work and what it does?

just had safari crash and it didn’t must not have saved in the indexdb can you help me retrieve my game, this is the second time it has happened, first time i tried to export it before i had to restart my computer and it didn’t export manually that time. can’t justify a 3rd restart. thank you

How do blueprints work? When I click the drop down, all I see is default and no way to make a second or a new one.

Can someone explain how resistances work? What elements have resistance to what? And how does the tower resistances stack? i.e. if I have block, and elemental resistance, and universal resistance, in both absolute and relative, then I’ve got 5 different reductions of damage – do they all apply? in what order?

Is there a point to making the max level for Regeneration under Defensive upgrades infinite? If a cube causes a large enough damage to the tower, it will die immediately, and if the damage does not kill the tower, it will heal itself in one second (or a fraction of a second if the upgrade cap is set at above 100%/second). I have used/wasted a lot of resources on this upgrade

Hi. First of all thanks for a great game. Right now i have only two problems with it. First is lagging after 1500+ wave on every difficulty. And second is local saving. Please consider cloud saving for this game so we wont copy/paste save every time we change pc (i have to do it 3-4 times in a day).

I keep getting Javascript errors that prevent the game from loading, except in Private mode. Does anyone have any clue why this keeps happening?

How do I gain additional blueprints? Dropping down only gives me one: the default.

Each time you tier up you unlock and additional blueprint.
