Alien Shooter Experiment

[Danny Hosford]

AlienShooter is presented in a top-down, third-person view (3/4 perspective), and takes place across nine levels of increasing difficulty. The main objective of each level is to eliminate all the aliens. To do so, players must access all of the areas that the level has to offer (by completing tasks such as reactivating power generators, destroying walls, and disabling force fields, etc.) and removing the alien threats within. Later levels feature teleportation devices, which spawn enemies indefinitely, and can only be destroyed by special explosives scattered throughout the level.

Characters have four stats: Strength, Accuracy, Health, and Speed, and players have the option to play as either a male or a female character. Male characters have higher strength, and higher health stats, whereas female characters have improved accuracy and higher speed.

Once exterminated, alien enemies drop loot consisting of money, health, ammo, and other items. Between levels, players can purchase upgraded, more powerful weapons in the shop, along with permanent stat upgrades. Temporary upgrades can also be purchased, including "Lives", Body Armor, Attack Drone, etc. Most items in the shop can also be found scattered throughout the levels.[3]

In the early year 2030, scientist from M.A.G.M.A Energy Corporation created the bio engineering creatures by mixing both DNA animals and alien cells from a meteorite they've been found. Those creatures have been successfully created such as mutant frogs/spawn frogs, multi-armed bipeds/raptors, giant spiders, and tank rhinos. However, something bad happens, the aliens plan to escape from their cage while using a teleporter device as their plans. Protagonist's task to eliminated the aliens inside of abandoned experiment lab places.As the protagonist explores the lab, the root of the problem is revealed to be a malfunction with an experimental teleportation device. Somehow, the aliens have managed to flood through en masse, killing the scientists and guards who were working in the lab. Delving deeper into the complex, the protagonist encounters ever more powerful aliens and realizes that all the teleporters must be destroyed. The game reaches its conclusion when the protagonist has eliminated all of the aliens and destroyed all the teleporters in the laboratory.

The final cut scene shows a single female spawn frog escaping the laboratory and running away. The story is continued in the first expansion, Fight For Life, and concluded in the second expansion, The Experiment.

The alien invaders from Alien Shooter have quickly become the dominant species on the surface of Earth. Humanity has had to hole up in protected and contained settlements. For over a year people have had to learn to live in these settlements and have become their own prisoners. But now a group of scientists have come up with an experiment to fight back and resist the invasion from decimating the human race. This plan calls for the creation of a super creature who, under control of humans, will fight the alien invaders and push them back. It's up to you to find this creature and set it free to fight the menace, but of course who's to say The Experiment won't backfire?

Alien Shooter: The Experiment is the second add-on to Alien Shooter. This new expansion pack adds five new missions to the game but unlike the previous expansion also introduces new playing fields such as houses, playgrounds. This expansion also adds new weapons and new enemies including a boss battle. One final addition that Sigma Team made, due to popular demand from fans, is the inclusion of a tougher difficulty level selection at the beginning of the game.

The original Alien Shooter was a pretty fun shooter that was sort of like a spiritual successor to the likes of Gauntlet, Alien Breed and Chaos Engine. It was a little shallow but provided plenty of intense blasting thrills, and made for an entertaining time. The Experiment isn't a full-blown sequel but is an expansion like Fight for Life which keeps the base gameplay intact but expands on the mythology a little by providing some new missions to enjoy. The story here finds the alien invaders from the original now the dominant species on Earth, with humanity now restricted to scattered settlements. However, when some scientists come up with a way to fight back, which involves finding a super creature which can be unleashed upon the invaders. And guess who gets the job of tracking this beast down? That's it, you, the player. What follows is basically the same as earlier installments, being an isometrically viewed shooter that sees you exploring a series of environments and basically laying waste to everything that gets in your way. There are five new missions here, which also include some new environments, as well as new enemies, weapons and a boss. You can even crank up the difficulty level if you really want a challenge. If you're into your hardcore shooters, then this is a fun expansion to a similarly themed game. There's nothing particularly new here, which is a little disappointing, but there's no denying that wasting aliens is fun. The visuals are solid but a little lacking in personality and overall, this is a solid addition to the series.

Alien Shooter released 1st January 2004 bySigma Team Inc. andpublished by Dusk2Dawn Interactive for the PC.This shooter has two playing modes: campaign and survival and two characters. Features also include unlimited playtime, ten levels, 9 unique weapons and 6 types of monsters to defeat.

Your mission is simple: clear the base at all costs. You will be provided with explosives to help you gain access to the teleports from where thousands of pitiless creatures pour.

As you earn your pay, you can equip yourself with additional weapons in the arming area and biomechanical implants that will make your fighting abilities super human.

The alien invasion has begun, we have one chance, and that is to stop them cold in their staging area. Do not allow them escape this facility, you are our last hope. The fate of humanity now depends on you!

Add-on to Alien Shooter (also known as Invasion: Earth in the UK). Day after day, the hope for human survival is fading. Half of the Earth's surface is inhabited by the monsters. Now people have to dwell in specially made fortified settlements. Here they live, work, study, have children and invent new ways to fight the aliens.

Now the leading scientists of Earth are working on creation of the new monster species, which should stop the invasion. Will the scientists succeed? Can their plans be realized, or this can cause even a larger disaster?

The add-on features five new missions, new music and monster types, a new boss, new objects, and the ability to choose the difficulty level.

Dusk2Dawn Interactive Limited (D2D) was formed in 2004 and employs four full time staff members. The company says it utilizes the in-depth knowledge of respected gaming veterans to release titles that have strong gameplay elements and not just pretty graphics.

Ok, I'll download the steam demo versions, hoping they have the same problems.

That will require staying home for a while, so I can't say when I'll do it, hopefully soon enough.

Stay tuned ...

Alien Shooter

Demo installed, the problem here is that the exe is obfuscated (that is encoded in such a way to make it impossible to retrieve the pointers to the library calls) . In this situation, usually the "Hook / Hot patch (obfuscated IAT)" flag allows you to hook a limited number of system calls and, with some luck, that is enough for making the windowizing process to work.

But with this game the cursor movement must be detected in some peculiar way, in effect despite the successful hook to GetCursorPos (the system call that most programs use to determine the cursor position) the log I took doesn't show any reference to this operation.

Now, with an obfuscated game it is very difficult to guess what's going on whith unhooked syscalls, I'm downloading some older (and hopefully NOT obfuscated) game version to try to study it a little better.

update

GOG game release is not obfuscated, so it is a good case study. In effect, this one has the same cursor problems than the Steam release. To fix the cursor position is necessary to set the "Input / set WM_NCHITTEST" flag, but sadly the same trick doesn't work on the Steam release.

I've got to understand why ....

update

Ok, fixed, you have to set also other Input flags. The attached export file makes Alien Shooter Steam demo run in window with fixed mouse control and 1:1 scaling ratio. Unfortunately, if you set a custom window size, the game doesn't scale the rendered frames. Another mystery to solve.

This is the export for "Alien Shooter 2 Reloaded demo Steam release" (one must be very specific, since there are tons of different versions of this game available!). It works more or less with the same features and tricks as the former episode (still obfuscated, no rendering resize, need for WM_NCHITTEST mouse processing) plus the need to hook D3D9.

No traces here of the FreeLibrary errors and crashes, I hope that the new setting will fix things for you as well, but in case just tell me.

Now I think I'm going (to relax and ...) to mind the resizing problem: it is very curious that a D3D game would show such a behaviour. It sounds quite interesting. In the meanwhile, please mind that aliens won't bother us earthly creatures!
