I got alot of idea while I'm at school :P
1. Class system
4 classes
1 Green beret
Allow to build green beret soldier for 750 (lower price), also 2 more soldiers which is using M4 Carbine
Allow to get M4 Carbine when starting instead of M16
2 Combat medic
Able to build a healing station which will heal the soldiers in the area
Have a better healing gun instead of the normal one, like having more ammo at starting and heals more
3 Paratrooper
Allow to build Paratrooper Squadron which cost 5000 and builds 20 - 30 paratroopers
When you start/respwan, you're allowed to airborne with parachutes (Like give you a map and choose where to spwan)
4 Scout
Runs faster
Have a better shotgun instead of the normal one, having more damage and longer shooting range
2. Make this game on steam so we will be easier to play with others also be more popular...?
3. Add a gunship with works like the paratrooper plane but only with turrets
4. Add a ammo station which will be able to buy the special weapon's ammo, like M4 Carbine's ammo but it's expensive like 1k for 100 ammos
If you add the class system, make it unable to get other class's hats like medic getting scout's hat
That's all! Thanks for watching this
