What’s your idea about missions that you have limited gun fires?
For example you can fire 1000 times only.(or more?!)
This way the player have to manage his fires.
It can be endurance too and with a powerup that increases your fires. And when your fire numbers reach zero you will lose mission
The number of fires you can do is based on these things:
1.waves
2.difficulities
3.weapon
Sorry for bad english.
This would be extremely hard to program and/or balance. It would be basically and dont die mission on harder difficulties as you couldnt afford losing power.
The thing is, some weapons have a much higher DPV than others. Any automatic weapon would be pretty much useless in this scenario. How would you even balance that out?
1)what is DPV
2)there are two ways:
A)this type of mission is just for some special weapons
B)the amount of 1 fire will be like the amount of when you click just once with the automatic weapons.
Hope you understand (B)
