$ will increase money income by 10 * number of $s bought. Soldier will spawn 10 soldier units, this costs 100 money. Can be killed by the environment. Minigun soldier will spawn 5 heavy units, this costs 150 money. Can be killed by the environment. Tank will spawn a single tank unit, this costs 175 money. Powerups can spawn which give you either tear gas or missile. Tear gas will stop any enemy units that touch it, it can be destroyed by a missile. Missile will ask for a missile to drop onto the battlefield, however the missile is random and can kill friendly units and tear gas drops.
Update: Lowered music volume. Reverted to the original spawn system. Added tear gas and missile powerups. Added a money making system. No longer get 10 every second from start and now spawn with 1000 money instead of 0. Soldier now spawns 10 units, instead of 1. Now costs 100. Heavy now spawns 5 units, instead of 1. Now costs 150. Tank now spawns 1 unit. Now costs 175. More backdrops! Clouds and Snow lands. You can get money for killing units and getting units to the enemy base. ----------------------------------------------------------------------------------------------- Music by http://soundbible.com/1512-Civil-War-Drummer-.html and http://soundbible.com/2078-Gun-Battle-Sound.html Explosion sound effect by http://soundbible.com/576-Barrel-Exploding.html This took awhile to make, I started development on this yesterday (1st of May 2016) and hoped I would finish it before the day ended, but it took considerably longer due to reasons. Oh well. Enjoy!
