Tank upgrade

[BlakeMW]

The cannon is better than the machinegun against biters. Unless you have a bunch of of damage upgrades for bullets, your tank machinegun won't do much damage to even medium biters. The cannon kills mediums in one hit.

Unfortunately the cannon is still severely lacking against biters compared with grenades - grenades are fantastic things for wiping out biters and spitters which are hounding the tank, both cheaper and more effective than the cannon shells. And the Tank's armor is high enough to almost entirely mitigate self-damage from the grenade so you can safely detonate them on the tank when surrounded by biters. And then there are poison capsules which are not resisted by any biters and are virtually always more cost-effective than cannon shells. Cannon shells are only really good against spawners.

Imho tank is great* as it is, it just needs to be renamed to "bulldozer" so people know how to use it accordingly. It's a shame shells are effectively useless, but you don't need them, just poison worms, ram nests and ignore moving targets, and after there's a lot of them lure them to your perimeter . . .

*for a mid-game armor/weapon combo.

I think part of the problem with cannon shells is the mixed damage of the explosive shells, and how difficult it is to hit targets near the tank. If they dealt only explosive damage and hit groups of small targets easily, they would wreck piles of biters and leave your tank unscathed.

Behemoth biters and spitters are just so powerful that anything you use against them is ineffective if it's not upgraded really far past its starting point, and the tank just doesn't upgrade very far. Turrets do upgrade a lot, but you can also just throw down more turrets.

Also the spawners send waves at you so rapidly there's no time to mow them down and switch weapons. Either you shoot the spawners while being attacked, or you just ignore the base. There's no way around that.
