Main Section
Grind money and collect upgrades AS SOON AS POSSIBLE
Why? Because the more stages you finished, enemies will have more health. Even in earlier stages. Which is, of course, a problem if you need grind at later stage without a good upgrade.

The less money you have on field, the more you earn
Suppose you have 1999 money. Notice that, with maximum earn-per-kill upgrade, you will earn 22.5.
Now let's say you have 2000. You will earn 21 per-kill.

This mean it's actually better to spend money and have solid defense rather than saving and hope you will get nice end-stage bonuses. Remember, you will gain not only from current saving, but also from current finishing wave (100 per wave if I'm not mistaken. So if you clear the stage at wave 50, you will get 5000. Not much, but better than nothing).

Loan doesn't have any effect, so -2000 is still less than 2000. SPEND IT AWAY.

Slot upgrade ONLY upgrade damage
At maximum perk upgrade, slot can be upgraded thrice.
And it seems it also raise your unit rank.

Sadly, only damage that affected by slot upgrade.
Health and rate of fire must be gained by upgrading the unit itself.

Oh yeah, slot upgrade also THE ONLY WAY to upgrade turret damage (credits to Milesvond)

Regen seems based on lost health
I really need confirmation, but it seems unit is very tanky with less health they have.

It seems like this:
Say you have unit with 100 hp and 5% regen.
Say at t=1, it take 80 damage. It seems it will regen health at 80 * 5% = 4 health.
Say it's t=2. From the regen before, now you unit lost 76 health. The health it will regen seems 76 * 5% = 3.8 health.

After get the formation, I'll try to not spend any.

@apple:
This is my playstyle
1. Buy loans upgrade
2. Get ALL upgrades, units, etc etc when keeping your money as little as possible, favorably below $2000. Because like you said, saving money to spend it later is actually put us in disadvantage. After that, getting wave 50 is easy.

@Col.SoapyWater[FRZ] so the more money you have in the bank, the less you get from killing zombies? how does that help when trying to gain money for upgrades and other recruits if your spending it to gain more when you'll just spend it again?

@apple: It's kind of counter intuitive, but the more money you have (on that stage, not in the main menu), the less money-per-kill you get.
For example:
When you have $1999, when you kill zombie, you will get $22.5
When you have $2000, you will get $21
When you have $30000, you only will get... I forget, about $1 - $5 per zombie kill

i don't understand how the 'The less money you have on field, the more you earn' part works :P

ADDITIONALLY, the slot upgrade increases the damage on TURRETS, not just troops.

No comment about the fact there are easy to miss upgrades that let you increse the ammount of cash you can earn from kills? or that in gold upgrades you can get 4x the speed?
