 * **Nuclear Winter** - adds nothing, takes nothing away :) - in fact, it is not so much a defensive weapon as a double-edged one. It floods the area with "radioactive" fallout, which is ordinary soil. If you do not have at hand any weapon that digs up the terrain, and for that a shield (preferably disposable), then after such "fallout" you will have to shoot yourself - because being underground is otherwise impossible. Alternatively, **White Flag** always remains.
 * **Long Schlong** - a special weapon :) - Costs a lot, doesn't really help with anything (except possibly digging yourself out but only when slightly buried but it has a cool name and looks cool :) - It can be activated independently of other defensive weapons and remains active until the end of the round (it cannot be deactivated).
 * **Lazy Boy** - it is not actually a defensive weapon. It is an aiming aid. When it is activated, the tank tries to aim at the nearest enemy and automatically adjusts the power of the shot and angle. If it has too little energy, it can sometimes aim wrong (it uses a method like **Cyborg** to aim). Like **Battery**, it does not deactivate other defensive weapons when used. Note: There is no point in activating this weapon before the round, targeting will not take place because there is nothing to target yet.

+* **Lazy Darwin** - works just like **Lazy Boy** but targets the weakest opponent. In this weapon, after automatic targeting, "visual targeting" remains active, so you can easily change the target and independently select another opponent by seeing if you hit him.
-* **Auto Defense** - activates the mode of automatic activation of defensive weapons. After its activation, the tank automatically activates the strongest shield it has (consuming it, of course) at any time when there is no shield (also between shots of other players). At the same time, if the tank's energy level drops below 30 units, it automatically activates **Battery** if it has it. This weapon remains active until the end of the round and is indicated by the letter "A" before the name of the active defensive weapon in the status line. It is the second defensive weapon that does not deactivate other defensive weapons when used.

Fire/Space/Return/Esc - ends the "spying". This is the last defensive weapon, which does not deactivate other defensive weapons when used.

 * **Nuclear Winter** - nic nie dodaje, nic nie zabiera :) - w zasadzie to broń nie tyle defensywna co obosieczna. Zasypuje teren opadem "radioaktywnym", który jest zwyczajną glebą. Jeśli nie mamy pod ręką żadnej broni odkopującej teren i do tego osłony (najlepiej jednorazowej), to po takim "opadzie" będzie trzeba strzelić do siebie - bo będąc pod ziemią inaczej się nie da.

 * **Lazy Boy** - nie jest to właściwie broń defensywna. Jest to wspomaganie celowania. Po jej aktywacji czołg stara się wycelować w najbliższego przeciwnika i automatycznie ustawia siłę strzału oraz kąt. W przypadku posiadania zbyt małej ilości energii może czasem wycelować źle (do celowania stosuje metodę taką jak **Cyborg**). Tak jak **Battery** nie dezaktywuje innych broni defensywnych w przypadku jej użycia. Uwaga!

+Christmas colors edition! Can you carve a quarter of a page of memory from two decades old code? Sure @Pecusx can! So finally we have the most requested feature - C0L0RS on the game screen, adjusted with Adam's help.
+Press [TAB] twice in the main menu to switch to a screen with colors.
+Other (dubious) improvements:
+- New Lazy Darwin, it is spectacular, check it out!!!
+- Smoke Tracer does not smoke when targeting with Lazy Darwin
+- Lazy Boy works well with joystick
+- Another fix for self-destructing tanks shooting low angles (0-4 degrees)
+- New, better tank shapes by Adam
+- Barrel start point correction fixes very rare aiming issues
+- Soil slide after Hovercraft usage optimized

+###### Version 1.21
+2022-12-10
+
+We couldn't resist! This is the Senior Executive Director's Cut.
+By virtue of byte misering we squeezed in a few new features:
+* new selectable tank shapes - change the controller enough times to get a different tank model
+* lonely bad pixel after Liquid Dirt fixed
+* mountain colors (or shades) possible, switch with [Tab] in the main menu
+* active controller number display in the game, store, and inventory screens
+* a very special terminator mode for Moron
+
+
+###### Version 1.20
+2022-11-23
+
+It's the final cut. Director's Cut.
+We squeezed the code and saved some bytes to add the joystick/controller selection. No more fights for the stick, up to 4 players can have fun with their own manipulators. And the fifth one can still use the keyboard :).
+Our most prolific testers Arek and Alex called for a number of fixes. Thank you, guys!
+* Players can select their controllers.
+* Better Auto Defense symbol in the status line.
+* Battery performance in AI and Auto Defense fixed.
+* More accurate and faster Laser.
+* Boost For Gifts includes a secret, quite powerful weapon.
+* Points counting fix-up (edge cases eliminated).
+* Long lists in inventory and shop were pointing to a weapon outside the screen. Fixed.
+* Lazy Boys now remember the last weapon used.
+* Especially for XEGS - SELECT key changes the joystick similarly to TAB.
+* Rare P/M glitches fixed.
+* ExplosionRange variable glitched (rarely) due to byte/word mix-up. Fixed.
+* Bouncy Castle was bouncing the laser from inside. Fixed.
+* Shielded tanks were autodestructing when shooting with angle 0. Fixed.
