The weapon modes are on the left. Each of the three upgrades alter the projectiles your weapon shoot and once you have purchased one or more you can switch between them.
They're bound to the keys 5, 6, 7, 8




rest will come soon




Standard (5)
You start each level with these. Nothing special to say about them, I guess.

Buckshot (6)
Very effective against the green cows who don't walk in a straight line. Also instakill the big purple cows if all projectiles hit.

Piercing Shot (7)
Same like the standard rounds except that the projectiles go through all enemies. So if you had several grey cows lined up, you would kill each one of them. But perfectly lined up enemies never happen, so the usefulness of ths upgrade is rather questionable.

Explosive (8)
Instakills literally everything. Therefore very effective against all cows and zombies who can take more than one hit.


Personally, I like the Buckshot most, closely followed by the Explosives.
The Piercing Shot however seem like a waste of $$$ to me.
　
　

　
　
Ammo upgrades affect the clip size, reload speed, firing speed and add a laser sight thingy.
They're bound to the keys Z, X, C, V respectively.


rest will come soon


I usually upgrade clip size and reload speed twice each and if I have enough $$$, the firing speed twice as well. The laser sight is a waste of $$$ once you're good at moving around.
