Detailed Instructions
Welcome to VectorTD
The year is 2088, Earth is under attack from a race we have codenamed "Vectoids". Over the last few years we have managed to refine our abilities to defend ourselves, but we do not know the origins of these Vectoids, or why they are attacking us.
VectorTD is the codename for a computer simulation designed by one of our top boffins, Professor David Scott Jr. The simulation is designed to train commanders in the art of defending facilities from the ongoing threat of the Vectoids. The simulator comes compiled with 8 of the most common paths used by these facilities and the full range of attacking towers at their disposal.
The aim of the simulation is to eliminate the Vectoid threat before they reach the end of the path. You do this by constructing towers along the path. Success is not based solely on the types of towers you select, but where you place them and what upgrade and bonus options you take.
Use the buttons on the right to find out how to master the simulator and achieve the highest score.
Vectoids
Blue Spinners
This is the most common type of Vectoid, we have found that blue lasers do the most damage but they seem to take less damage from purple lasers.
Red Shredders
One of the first types of Vectoid encountered. We quickly found that red lasers and rockets caused the most damage, green lasers seem to do very little damage.
Green Flyers
Fortunately all our defenses can cope with air targets, the red lasers do not do so well, but green lasers do heavy damage.
Yellow Sprinters
These are a real pain! They travel much faster than all of the other Vectoid types, fortunately our blue laser based towers can slow them.
Big Purple Box
Don't let the simple geometry of this Vectoid mislead you, it is as tough as the best of them, its main weakness is purple lasers, but seems to resist attack from blue.
Hard Grey + Bonus
This Vectoid has increased armor and is harder to destroy. On the up side they are quite rare and they escort a power cell which is worth 1 bonus point.
Orange Regener
This Vectoid can heal itself over time, it is best to remove it as quickly as possible.
Orange Spurt
A Vectoid that is able to increase its speed for a short period of time.
Attacking Towers – Explained
Green lasers 1, 2 and 3
The Green laser towers fire a beam that does constant damage the whole time it is focused on the enemy Vectoid. Laser towers 2 and 3 have so much power that the beam is reflected off the target onto nearby Vectoids. Reflected beams do 100% damage.
Red Refractor, Little Red Spammer and Red Rockets
The Red Refractor is a laser based tower, the red light is refracted through the target and hits all other Vectoids around it. The damage the refracted beam does decreases as the distance increases. The Little Red Spammer fires heat seeking rockets at random targets in range. The Red Rocket tower is one of the most destructive towers at your disposal, the rockets it fires are capable of acquiring new targets mid flight.
Purple Power 1, 2 and 3
The purple laser towers are similar to the green lasers but instead of a continuous beam they store the energy up and release it in a single high power burst. The 3rd tower is so powerful its beam slows the target as it drains its power.
Blue Rays 1 and 2 and the new Rewinder Tower
Blue ray towers reduce the speed of the target. The 1st tower can target upto 4 different enemies in a single shot. The 2nd focuses its attack on a single target which stuns it.
The rewinder tower teleports the target back to a point in it's past. Use at the end of your defenses to make those Vectoids get another taste of your towers.
Attacking Towers - Options
Upgrades
All attacking towers can be upgraded 9 times (to level 10) Each upgrade costs 50% of the cost of the initial construction cost. Each upgrade you do will increase the range of the tower by 5% and damage by 45%. Towers can not be downgraded, however the money you get from selling the tower does include the money you have spent on all upgrades.
Attack Modes
Most towers can be instructed on how to acquire targets. The 3 modes you can select are Close, Hard, and Weak.
"Close" will instruct the tower to select the closest Vectoid when it is looking for a new target. "Strong" will make it select the least damaged target in range and "Weak" will tell it to target the most damaged target in range. Use these 3 modes to create the best setup, using modes like "Strong" on your highest damage towers and "Close" or "Weak" on towers close to the exit.
Selling
At any time you can sell a tower for 75% of the total money you have spent on it, including upgrades. You can only sell attacking towers, booster towers can not be sold.
Bonus Points
The "Hard Grey" Vectoids always seem to be transporting a yellow energy cell. Destroy this cell to receive a bonus point. Bonus points can be spent on booster towers or can be used to upgrade your interest rate or buy you 5 extra lives.
Damage and Range Booster towers
There are 2 types of booster towers, both cost 1 bonus point to construct, neither have any form of attack. Instead of attacking they increase the damage or range of any tower they are linked to. They automatically link to towers you place them close to. The link is indicated by a line.
The damage tower will increase the damage of all linked towers by 25%. The range tower increases the range of linked towers by 25%.
The effects of the booster towers stack. This means that a tower in range of 2 damage towers will have its damage increased by 50%
Increase Interest
At the start of each level your banked money receives interest. The interest rate can be increased by spending a bonus point on the interest rate option.
