Ok so first i`ll explain how i managed to raise until 5,000,000 Bz. (for real)
At the beginning of the game DON`T BUY ANNYTHING FOR THE GIRLS YET. you will realize that everything is "overpriced" but that`s not the reality beacuse the drops after patrol works will raise your Bz account like you never imaginated, now this being said let`s continue.

The first week of the game focus in work out/shooting practice/swimming and do ocasional patrol work. It all depends on the drops you get, if you need a little more profit buy the repellent (cost 20k but if you found nothing on the desert you win 40k), don`t buy any support of the girl it, it not worth it, only if you really need it.

My first drop ever was the burning rock (510k) which dropped from the fire alien (it`s like the 3th in appear) so pretty amazed with how much it worth, after you get this or the plutonium or lucky pendant (too much luck if you found it) go to the Cafeteria and buy the Uzi, then buy kevlar, then shotgun, and the electric armor, these loadout will make a lot easier and effective the patrol work, making you win until 160k after defeating the aliens (plus drops).

After that you`ll realize that making money is not that hard, now having all these combat equipment you are free to buy non-combat items as you wish, the drop items is below for more info.

Also but not least go check the combat guide too to use your weapon at their 100% effectiveness.

This section is properly to change in the time i test the weapon i missed the first time:
- If the alien is using a shield, you can penetrate it by using the knife, you will barely damage but that`s better than nothing.
-If your armor have been reduced to 0, you can change to another armor and on...
-Electric armor makes you immune to the electric sparks attack.
-Ceramic armor makes you inmune to heat attacks (burning sand for example)-
-Start by using the most stronger weapon you have, in my case i always start with the rpg so i can begin doing a lot of damage to them.
-EMP pistol does less damage than the normal pistol but instead it does a lot of damage to electric aliens (Crisis).
-Change to Uzi or shotgun depends if aliens are using or not their shields, if not, use the Uzi to attack 2 targets at same turn, if 1-2 are using them, go for the shotgun and make more damage to the defenseless one.
