Merge Gun: Shoot Zombie is a zombie-themed mix of "shooting gallery" and idle merger. That means precisely combining weapons, waiting for free money - and then taking those stuff to stationary fight.
In terms of graphics, the game uses recently popular no-shaded low-poly style for all aspects. The enemies will be primarily plain undead from several types - football payer, beach girl, or scuba diver. There are also spiders, bats, giant zombie bosses, and dragons - all can be viewed in the gallery after unlocking. Their simple 3d design fits the environment well. You'll be killing those zombies in various sceneries - some pirate beach, wild west, or snowy woods - and they look pretty consistent and convincing.
The mere gameplay part is relatively simple. Just drag and drop a gun on the other one of the same type - and you got one of higher level. To get more guns, you can buy it - or just wait for a crate. Merging will give you experience and new levels eventually. That means more gun spaces & the possibility to get stronger ones. Also, guns will magically generate money when idle - and you can spend that money on new weapons or some generic updates.
The fun part begins when you bring one of those tools (usually the strongest one) to a zombie fight. You'll just need to tap the screen & drag it to target some monster - shooting will begin automatically. Still, to use ammo effectively, you'll need to aim quickly & accurately. When playing the "day" (campaign) stage, every 5 rounds, you'll meet the boss - and the environment will change afterward. There's also "endless mode" for a more significant challenge - enemies will spawn continuously, stronger and stronger.
Aside from those things above, all the rest are ads or premium currency offers. To get bonus crates, wheel spins, daily gifts, etc. - you'll need to pay with your time - and there are even forced ads after battles.
