Thermal Cannon

A powerful fire cannon that rips the very flame from torchwood like plants, more powerful torchwoods give more of a charge, in consuming the flame however the torchwoods get temporarily disabled and do nothing at all.

Better torchwoods take longer to drain, but give more flame in a shorter time space than weaker torchwoods, as it drains the flame it acts like its downgraded-versions, until it gets to the last version and gets disabled, and eventually upon re-igniting becomes the regular upgrade.

Upon being clicked it releases the fiery charge in a great blast, that can reach long distances, cover multiple lanes and hit multiple zombies.

A small charge will cover a 1x2 or so radius, larger ones will cover greater distances, able to cover 3x9 areas in a long lasting blaze.

For every second the fire lasts, it does the damage to everything in the cone, making up for the relatively low damage.

The rest will be completed tomorrow.

Didn't have time to complete it now
