The only way to make it easier to play CKZ2 is to find ways to build up your weapons. While other players may have various ways of building up their weapons, here are my suggestions.
Get enough gold resources
Download tapjoy/glu games and get daily bonuses for glu gold (especially Gun Bros). This is a lot of work but unless you want to spend cash, this is ain’t a bad option. Many of the decent weapons fall under the 300 glu gold mark (except for a grenade launcher). When there are discounts, take advantage of them.
Start off with Basic Weapons
I know. These are a bit pathetic but you have to start somewhere. Here are those you would normally start off with: Baseball bat, Mini Uzi/Block-11, AR-19 Basic, 12 gauge shotgun
Get the weapon packages, cash-based/free weapons and “cheap” gold weapons
You can get the starter weapon package for the ZRU-12. Also you can try the HPK-5 SMG (low end SMG but better than AR-19) and the Block-19 handgun or MP-942. Definitely get the Commando sniper rifle to rack up waves in the Survival Mode to get cash. Get the black katana in 15 days so you can throw away the baseball bat. Or the Fireman's Axe is also a good option.
When you have enough cash, get the 9mm Technic SMG (but if you already have the ZRU-12, save up the cash for the Demo X400 - the cash equivalent of the Boarles .50 sniper). Upgrade your 12 gauge shotgun to the Police Model (not the best but at least better).
Then get the 77 glu gold package. This will greatly improve your arsenal. It will now be:
ZRU-12 Advanced, MP-643, Ancient Katana, Police Model Shotgun, Demo x400 sniper rifle (No Exotic Weapon yet).
(Update) There is also another gold package that offers a grenade launcher. Will try to check how much it costs.
With this lineup, I should say you have a fighting chance with most missions. Just have defibulators and beacon grenades handy (if you have).
Save and earn until you can afford
Your wishlist individual weapons should be as follows (my priority). If they are offered at discounts, get them.
1. Desert Hawk (gold)
2. 10 Gauge Supershot (gold)
3. .50 Light Machinegun (cash)
4. C-16 Auto (gold)
5. The Exterminator or Anihilator (or try check the Comrade)
6. Streetsweeper Auto Shotgun (gold)
Once you have these weapons, you should be somewhat safe by this.
If you really save up for the Shooter's weapon package and get it, give yourself a pat on the back for all the hard work. You can also try your own way of getting the best weapons.
Comments and feedback welcome. Of course it is your choice if you want to use cash to buy some of the weapons. If ever you do, the best investments are the Streetsweeper and the Shooter Weapon Package.
The Wolf Pack are my friends, like all others whom I have the pleasure to know. You have my respect because you deserve it - the same way I expect this respect from you as well.
