Shockwave: Invasion Earth strategy

Mission 1: Egypt
There are three objectives in this mission.

Valley of the Kings
Destroy all aliens here in order to complete the first objective. There are eighteen aliens to be destroyed. (10 Tripods and 8 flying Scouts). Be careful; one Tripod slowly tries to escape on the left of the path. If you are slow, you may not be able to destroy it.

Giza
Destroy all aliens here in order to complete the second objective. There are fifteen aliens to destroy. (10 regular Tripods, 2 strong Tripods, and 3 Scouts).

Cairo
Destroy all aliens here in order to complete the third objective. There are twenty aliens to destroy and one Boss. (4 regular Tripods, 8 stronger Tripods, 8 Scouts, and 1 Fortress). To destroy the Boss, use missiles. Avoid approaching too closely. Launch one or two missiles from a distance, make a U-turn, and repeat the approach.

Comments
To accomplish this mission no other aliens than those present at these three sites need to be destroyed. However, try to destroy the three Tripods present on the refinery site, in the middle of some fuel tanks. If they are destroyed and the refinery is left intact, a bonus Refueler will appear later on the left of the path.

There are four possible Refuelers in this mission. The second is determined by the outcome in the refinery site, and the fourth is appears only if the first two objectives are met. Always check that the Refueler has stopped turning before allowing it out of to pass out of range. Your ship may sometimes refuel twice. When a Refueler is spotted, do a refueling, destroy any aliens that are past the Refueler, and then return to the refuel again.

At an objective location, it is generally better to destroy the flying aliens first, and then the ground aliens. Try to save the missiles for the flying aliens.

Unless a high score is your goal, do not waste time and energy by destroying all the aliens on your path. Stay focused on the objectives.

Comments
This is a very easy mission. Shoot all the alien air units, then attack the ground forces. Use the Refueler in the Andes and fly directly to Lima and shoot all the way to the end.

Las Vegas
Destroy all aliens here in order to complete the first objective. There are twenty aliens to destroy. (3 Tripods, 5 Collectors, 7 Scouts, and 5 Interceptors).

Riverside
Destroy all aliens here in order to complete the second objective. There are twenty-five aliens to destroy. (4 Tripods, 7 Collectors, 3 Scouts, 5 Interceptors, 3 Mobile AA, 1 Heat Seeker, and 2 Swarms). The four Power Cells, but not the Prison, must also be destroyed.

Pasadena
Destroy all aliens here in order to complete the third objective. There are nineteen aliens to destroy. (3 Tripods, 3 strong Tripods, 2 Collectors, 3 Interceptors, 2 Mobile AA, 5 Heat Seekers, and 1 Swarm). The four Power Cells, but not the Prison, must also be destroyed.

Burbank
Destroy all aliens here in order to complete the fourth objective. There are twenty aliens to destroy. (6 strong Tripods, 3 Collectors, 3 Interceptors, 4 Mobile AA, 3 Heat Seekers, and 1 Scout). Be careful; two Mobile AA units quickly try to escape on the left of the path. If you are not fast enough in the beginning of this objective, you may not be able to destroy them.

Los Angeles
Destroy all aliens here in order to complete the fifth objective. There are fifteen aliens to destroy. (5 Scouts, 4 strong Tripods, and 6 Swarms). New fast moving craft called Cobras also must be destroyed (their number depends on performance of the previous objectives). Twelve Power Cells must be destroyed in order to free three Prisons. Be careful with the satellite dishes. Do not destroy more than one.

Comments
If no buildings are damaged in Las Vegas, two bonuses will be available: The first Refueler is going to be full, rather than partially filled (this Refueler is not visible on radar because a tripod is at the exact same position). An extra Refueler will be available in Riverside, far on the left of the path, and invisible on the radar.

Protect the atomic power plant from the Collectors walking towards it (or your ship will be destroyed) and also save the six close towers from the Tripods. If they are saved, an extra Refueler will be available on the far left of the path in Los Angeles.

After Pasadena, in the Refinery region, there is a partial Refueler that is invisible on radar on the right of the path.

To destroy a Swarm, just shoot the immobile one.

Destroy transports
Destroy all transport vehicles and aliens in the first section to complete the first objective. ICE will state when this this stage is completed.

Destroy second transport group
Destroy all alien ships and transports in the second section to complete the second objective.

Destroy alien cluster
The third section is a little tricky. ICE will state that it might be acceptable to just fly by this cluster of aliens. However, this is the third mission objective, so everything must be destroyed in this region. The aliens also will leave the screen, so be careful not to let anything escape.

Construction site
The fourth section, and last objective, is a construction site that ICE says to destroy. It has a line of alien ground-to-air "Directors" that can cause extreme damage to the shields of your craft.

Comments
At the end of the mission, there is a line of alien ground-to-air "Directors" that will fire at your ship. Destroy the center Director and use the thrusters to move past them. This will complete the objective.

After the construction site, a group of aliens and a helicopter will appear. The helicopter is used to pick up Howser. If the helicopter is accidently destroyed, the mission will fail.

First Radar site (ground)
Find and destroy the first group of 5 Radars. (Listen to ICE).

Prisoner rescue operation (sea)
Free two groups of two barges of prisoners. Destroy the two leading alien boats without destroying the four barges and the cruise ship.

Second Radar site (sea)
Find and destroy the second group of seven Radars. (Listen to ICE).

Third Radar site (sea)
Find and destroy the third group of five Radars. (Listen to ICE).

Kennedy rescue operation (sea)
Destroy all the aliens surrounding the Kennedy. Between fifteen to nineteen aliens (less if the previous objectives have been successfully completed) must be destroyed. They are: two Skeeters, five Skimmers, four Submarines, three Scouts, and one to five Cobras (depending on mission performance). To end this final objective, destroy the final Boss; the "Morphing Tower". Do not get to close or it will start the morphing operation.

Comments
In the middle of the volcano is a "Pumper" that provides the energy for the Energy Fence located on land between objectives four and five. If this Pumper is destroyed, the Fence will be inactive; otherwise the Fence will be very dangerous.

On the Prisoner rescue operation (objective two) be very careful selecting which vessels to destroy. The lead vessels that must be destroyed are actually the last ones that will be approached. They are going in the same direction as the flight path. There are two sets of ships to destroy. Be very careful on the second group. There is a ship next to it. If the ship is destroyed, it will not be able to pick up the prisoners and the objective will not be completed.

Between objectives four and five are three giant alien boats. Destroy them and to get a bonus Refueler on the right of the path after the Kennedy location.

Between the objectives three and four (two Radar locations) is an extra Refueler not displayed on radar on the left of the path

Avoid getting too close to the Kennedy or risk collision. The "Special Force Shield" arming your aircraft may destroy the Kennedy, which is already fragile.

Excavator site
Destroy the three Excavators just past the wall of AA.

Second excavator site
Destroy the four Excavators past another wall of AA.

Egg site
Destroy the first Egg site. It is guarded by a group of alien units. Once it has been destroyed, use the thrusters to get past them.

Third excavator site
Destroy another four Excavators. ICE will tell you once you have completed this that there are no Egg sites left.

Second egg site
Destroy another Egg site. Use the same tactical strategy as used with destroying the first Egg site.

Dubway
Destroy the giant alien in the city of Dubway.

Comments
To destroy the excavators hit them with two nuclear missiles and some laser fire.

There are two ways to destroy the Egg site: destroy the Egg itself by using missiles and lasers on it; or destroy the surrounding alien units and the Egg will automatically be destroyed.

When the giant alien in Dubway is confronted, do not worry about destroying the buildings. The objective will be completed when the alien is destroyed.

There are a lot of aliens in this mission that do not need to be killed. Ignore them to save missiles and lasers. Use the thrusters to get past them.

There is a hidden Refueler in the canyon that is not on the radar.

Excavators and egg site
Destroy the two Excavators and the first Egg site. Remember that they are both heavily guarded, so be precise when attacking them.

Second egg site
Destroy the second Egg site. Use the same technique that used in Mission 6.

Third egg site
Destroy the third Egg site.

Robots
Destroy the robotic aliens. There are three of them and they are heavily armored. Use both missiles and lasers to destroy them.

Comments
The two Excavators in the first objective need to be hit with three missiles and some random laser fire to be destroyed.

Destroy the Fortress and receive a better Refueler later in the mission.

Destroy the four flying alien "Hunters" or they will follow your ship throughout each section.

Silo group
Destroy the Landing Pads and everything inside the first two Silos.

Second silo group
Destroy everything in the next two Silos. It is very important to destroy all Eggs in order to complete the objective.

Landing pads
Destroy all the Landing Pads. ICE will state that this is very important!

Spider alien
Destroy the spider alien.

Comments
The first Refueler is guarded by mines. To disable the mines and create a clear path to the fuel drone, take out the magnetic field underneath the fuel drone. Then, take out the two Radar stations just over the hill. There is also a Tripod alien that must be destroyed.

There is a giant alien directly after a Refueler near the end of objective one. Fly through fast and fire missiles immediately. The continuous fire from the missiles will destroy the alien. After completing this, fly back to the Refueler and regain the missiles that were lost.

The third Silo that must be destroyed is very tricky! After all the Eggs are destroyed, your ship must be maneuvered past a set of steel fangs. If your ship is hit in any way by the steel fangs, it will be destroyed. Use your thrusters to time the exit out of that Silo

In the last objective, a giant spider-type alien will confront your ship. Destroy the magnetic field first, then start using missiles on the alien. If your ship's resources have been depleted, there is a Refueler directly to the west side of the path that will recharge the shields and missiles.

Communication towers
Destroy the six communication towers to complete the first six objectives.

Snake alien
Destroy the giant snake alien to complete the final objective. Double back and hit it a few times with missiles and lasers in order to destroy it.

Comments
When destroying any of the communication towers, destroy the big unit first. After it is destroyed, pick off the little communication devices that surround it. Make sure that Refuelers are put to good use, because there is a group of swarming alien units that guard these communication devices.

After the first two O2 generators are picked up, a giant snake-like alien will appear. Do not get too close to it because the damage it gives out is deadly. Do not destroy the third O2 generator when trying to destroy the alien. If the third O2 generator is destroyed, the mission will fail.

Comments
Use the thrusters to bypass many of the aliens. Since there is only one objective, it would be wise not to waste much time on the alien units that fire at your ship.

When the mother ship is reached, there will be a Refueler directly above it. Destroy it. It will start firing when approached.

Watch the surface of the moon for magnetic fields. They can be quite annoying if your ship becomes stuck in one.

Scattered throughout the mother ship are "Pumpers". They do not fire at your ship. Take out as many as possible because it makes killing the Mother Brain easier.

When the Mother Brain is approached, try to destroy the aliens surrounding it first instead of hitting it directly. This might make the final objective a little easier.

Destroy the big octagonal human base on the moon near the beginning of the level. Elvis will be among the wreckage.

Shoot targets, explore the scenery, and view programmer's pictures.
