Low on content and variety, but provides quick action with a large number of weapons that can be modified into powerful killing machines.
You get to choose between five dogs. As always, just the first one is available, and the others must be unlocked by surviving the required number of minutes. Each dog has a unique perk, but it does not make a significant difference.
Although the gameplay is simple and uncomplicated, it delivers precisely what you expect from a game like this. It drops you immediately into a little arena where opponents never stop coming. Your mission is to collect money left by defeated enemies and use it at the vending machine to purchase new weapons.
The vending machine appears at random somewhere in the arena. The arena is very small, but it does spawn other objects, such barrels and crates containing extra money. Although the game uses a small number of colors, I like how it focuses on what is important.
Enemies are dogs, but their diversity is very limited because you only fight against normal, tiny, which occasionally explodes, and large, which take more damage. Each five minutes, a boss enters the arena. These are not particularly dangerous, and they mainly behave like normal enemies, but with a lot more health.
Each purchased weapon is placed around the dog. The placement is up to you, and it is critical because a gun can only fire straight ahead. Of course, the weapon determines the firing mode. So, you have shotguns that cover a larger area, machine guns that fire quickly but with limited accuracy, sawguns that fire a single bouncing saw, and so on.
There is room for ten weapons, and each weapon must reload after firing all of the rounds in its clip. Reloading and firing are automatic, so all you have to worry about is running around the arena and collecting money.
The selection in a vending machine is random (three options), but nothing prevents you from purchasing the same weapons again. Some are more useful than others, so you can save your money for the ones you are most comfortable with. If you have money to spare, you can also reroll the current offer.
Aside from weapons and rare bonuses for your character, such as extra weapons slots, health, or speed, the vending machine may also provide attachments for your weapons. Each weapon can receive a maximum of three upgrades (or more with the right perk), although all of them significantly improve it. For instance, there are exploding or bouncy bullets, faster shooting, and even double barrel.
Some even alter an apparently terrible weapon. So, if you give an accuracy upgrade to a machine gun that shoots bullets all over the place, you will gain a lot more control. If you are lucky, you can create a lethal weapon that destroys everything in seconds. One interesting choice is a rocket launcher with a twin barrel, homing bullets, and projectiles that escape one side of the screen and reappear on the other.
The bad news is that everything is final. This means that weapon placement, choice, and upgrades cannot be removed or modified. Although this is fixable if you pay attention, there is one issue that cannot be resolved.
The issue comes with the weapon ring surrounding the dog, particularly with larger guns. If an enemy finds itself inside this ring, you will be unable to attack it because no bullets can reach it. This becomes an issue later on, when the entire screen is crowded with enemies and your weapons are unable to keep up.
