14 day = 14 x 24h = 336 hr 1st M = 13, 2nd M =13+ 22, 3rd M= 13+22+28, by prediction, 13,35,63,97,137,183,235,293,357 using sequence solver: https://alteredqualia.com/visualization/hn/sequence/ 13h=1M 35h=2M 63h=3M (2.6d) 97h=4M (4d, extra M = 34h) 137h=5M (5.7d, extra M = 40h) 183h=6M (7.6d, extra M = 46h) 235h=7M (9.7d, extra M = 52h) 293h=8M (12.2d, extra M = 58h) 357h=9M (14.8d, extra M = 64h we may not reach 9M by end of 14 days = 336hr) the trend is , slower and slower late joining buyers, slower growth as it goes, why would buyer care spend 1000 coins in last day, most buyer would buy in early few days already.

first, I have all crystal augments (just to increase hull augment drop rate in container), but I use those container only augment most time; second, at your rank (3 gold star), I would say none, since later in Challenge, you can get far better augmnet (even free one in silver tier) and will not use those in the end. better get maxed gun and hull and module first, then better focus MU drone like brutus, miner, blaster (free player friendly and dont cost too much supply) crystal augments will be outdated soon or later (and sometimes free from container's purple color reward + challenge silver tier ) once you got Status Effect augment (like fire twins, ap rail, critical/emp/stun hammer, bounce vulcan, ap magnum) (Adrenaline augment never show in challenge, so those are safer buy, especially they are pure good than stock)

3 slot is for those low ranks since dev lock protection module slot to 1 in previous update (to reduce too much protection for low ranks), thus price for 2,3,4 is 500,1000,5000 tankicoins. old tanki who already using 3 slot is still 3 slot only, +1 = 4, +1 + 1 still =4 for them and you. -- module is not related to hull, unlike augments (hull or turret)

I have been saving upto 2300 coins at a time, (320 coins per month, that is 7 month saving, 14 challenges) then AP freeze was showing up in challenge, I skip AP freeze once before in its previous challenge because I was saving and waiting for AP titan at that moment; after think there are still 9 months ahead to saving another 2700 extra coins, I pulled the trigger and got the pass for AP freeze (as I already have EMP for gauss, smoky, long range AP rail, and I need a close range AP augment to fill the final gap of emp/ap tactics) saving for 5000 is hard, in short.

I got both from free UC when they just introduced, I rarely notice the difference when battle is so busy.

I am in to boost, here we go, 4th module slot., save 10 month of saving, now it coming in Xmas. ? Expect More and More free players like me to Jump in after see 2M. Note: 2 days after, still 250+ people buy? we have around 40k active players right?

Today i use freeze titan. Fire viking is ODing me when frozen by me, my titan survived his OD even i have no fire protection module, is freezing also disable viking OD damage boost?

i beat u, 5 ultra common Ultra + normal container. Worst mass open in 2021 tanki birthday, not a single purple level

better than nothing, at least free play now can create battle for free, make private parkour party or rankup party. make gold rain for your self. pro battle for free player is good for party and map practice.

shaft + heavy capacitor + camp drone. (25% + 60% + 200% dd = how to calculate? ) personally I use vulcan + Adrenaline augment + camp drone + fire immu hull (so 100% = 60% boost, low health = 30% boost, always boost) actually I think shoot and hide gun best to use camper drone, like (railgun, strike on light/medium hull)

Not even a single purple. only got 10 day premium and freeze resistance for paladin, at least saving me 256k for the useless hull resistance augment; (only good for making my same max GS as 9699 without 4th module)

so beautiful stack of color. should add "Drone Disabled" + "Boost Damage Disable" since the new update

you are too soft on this, dev already mentioned in one of QnA video, There will be no Second hull augment, so you cant mix and match your existing AP + EMP to achieve AP/EMP both protection, Instead, YOU WILL buy/lucky hunt ultra container to get SPECIAL EXotic or Mystic level container prize to get AP/EMP double protection augment, so even you already got ap, emp single augment, no use, you still need to hunt further to get NEW double protection augment, (same story as old module combo history if you are in tanki long enough)

I got fire resist and emp immu for dictator, freeze hammer? is it better than freeze smoky that available in crystal, anyone?

Twins hd is coming, so are twins augments, unlike smoky hard to aim, and low initial critical build up. twins constant fire make critical super annoying, I would see thunder will follow twins OP route for new P2W augment (even it is free in challenge and ultra container) the big problem is constance fire and medium range cover unlike AP freeze or Emp smoky/gauss/hammer/telsa or stun smoky/hammer/strile. a team of fire+freeze+stun+emp+ap smoky will be killed by a team of new fire-freeze+stun+emp+ap twins due to constant fire and knock off aim. Gun shooting game becomes more and more a magic power game, like wizard fight. Emp+ap+stun+fire are major things these day you cant avoid, AP is default immu you need to survive, module is your last protection, forget about health kit block by emp status effect, you can immu all, unless your team All paladin w driver drone to take turn covering each other with OD w 20s + 20s check twins new augment video to see what i mean, single free player just no hope, non team players in general is no hope against 4 buyer w 4 different effect augment in team in MM.

spent 3.3M crystal + 230 gold box to MU all 19 drones to Max 20/20, paladin to mk8 only left sprint drone at lvl 18. also ranked to legend 63 for 40k crystal extra. So Full Max crystal garage by legend 64 as non-buyer

At legend 100+, I guess you already have all maxed stuff crystal can buy. Maybe supplies?

No drone legends looks so noob now, Just get 100k brutus legends

Mission done, only got 1 purple. - railgun blood red shot effect. still 21 shot effect to collect in purple.

I am already almost get all drone maxed. True full crystal garage will be only way to counter changes and nerfs

Freeze immu is useful in CTF when multiple shock freeze camp, and they hull you prefer dont get freeze immu yet, so at least get freeze resistance, that is the only case you would buy that.

Nitro is hard to use, way to go with hammer/gauss crusade blaster - quick death style to get nitro mission done in CP

I got all resistance module, yes 19, from lucky container, only bought one fire resistant when they intro modules and at 50%, old days, challenge give 2 immu every time at bp, and resistance in free part. fire resistance is better than fire immu if u use vulcan ib fire bullet augment, since u need to overheat but not too much self burn. cold resistance only when u have nothing to equip

Always buy on last day, so you can compare first

All freeze augment and All hopper augment collection (miss jam)
