Act Fancer is a 1989 horizontally scrolling shoot 'em up arcade game developed and published by Data East. It features a cyborg battling against alien creatures, while collecting power-ups and defeating bosses to advance levels.

Action adventure/shoot 'em up hybrid similar to The Guardian Legend.

Join Lt. Ellen Ripley as she explores the Fiorina 161 prison colony in this six-stage action game with multiple level objectives. You'll have three weapons at your disposal in your effort to rid the colony of aliens: a pulse rifle, a flame-thrower, and a grenade launcher.

A motion tracker will help warn you of impending doom as you make your way through the maze-like air shafts and gloomy cell blocks. Access various computer terminals to receive level blueprints and select your assignments, which range from sealing off doors to rescuing cocooned prisoners. A password system allows you to continue your adventure until the final showdown with the Alien Queen herself.

Alien 3 is video game based on the movie sequel of the same name. The plot of the movie picks up directly after the end of Aliens. Ellen Ripley, the main character of the Alien series, is in cryo-sleep aboard the space ship Sulaco. Unfortunately, an alien or two has stowed away on the Sulaco, and wreaked havoc within the ship. Thus, it crash lands on the prison colony planet Fiorina 161. Ripley and the unarmed prisoners have to figure out a way to survive the alien who terrorizing the colony until help arrives.

Rather than sticking with the movie storyline and making more of an interactive story, Acclaim and LJN decided to make an action/adventure title instead, and good thing they did. It has a few flaws, but they can be overlooked easily enough by the average gamer.The graphics are somewhat above average for the original gameboy. A3 did NOT stick to the movie, but it at least does an average job of explaining why there are numerous aliens to deal with. Controls are VERY good, which is not very often in my experiences with original game boy games. Very responsive, with no lag between actions.

The proper game to the movie. Shoot and climb your way through a space station. As you progress with the game, you'll have to rescue prisoners which are imprisoned by the famous aliens. It's a valuable plattformer with a high difficulty rating. Another markable thing is the soundtrack, which is totally unusual for the alien series. It isn't the ambient styled chiptune, that you're used to, when playing titles of this series. Instead it is a nice done and quite fast action soundtrack.

Alien 3 is loosely based on the movie of the same name. Players take on the role of Ripley and must work their way through a series of expansive and multi-layered levels freeing humans that the Aliens have captured. There is a time limit on each level; if players cannot find and free all the humans before the limit ends, the game is over. Since humans can be trapped in a variety of places on each level, players must thoroughly explore the stages in order to advance.

Players can acquire and use several different types of weapons after finding their ammunition pick-up. Ripley can carry multiple weapons at the same time, but each weapon has a limited ammunition supply. Ripley also has a health gauge that decreases as the Aliens attack or after landing from a long fall. If Ripley's health gauge reaches zero, players lose a life. Finding and collecting the appropriate power-up can replenish the life gauge.

In addition to jumping and shooting, players can use lifts, open doors, climb ladders and even crawl through tunnels in the levels. Players can shoot while crawling, but cannot shoot while jumping. It is possible to shoot vertically or even diagonally while standing, however. Aliens are much faster than Ripley and generally cannot be avoided, so they must be shot. Each creature takes several shots from the standard gun to dispatch, but unlike their movie cousins, do not leave an acid pool when killed.

As with the Mega Drive and Game Gear versions, this is brilliant. Guide Ripley through the treacherous space-ship in a stunning platform adventure. Loads to do and powerups galore make it a winner.

Something has gone terribly wrong on the Suliaco's return trip back to Earth. Flight Officer Ellen Ripley finds herself alone on a prison planet, the sole survivor of her ship's unexpected destruction. Unknown to her and the inmates, she has brought an unwelcome visitor with her - an old and deadly acquaitence that could mean death for them all. Loosely based on the live-action sci-fi film starring Sigourney Weaver.

I usually don't like movie translation games, but this one's quite good. Good graphics and you get to be Ripley too.

Story:
The player takes the role of Chelnov, a coal miner who miraculously survives the malfunction and explosion of a nuclear power plant. Chelnov's body gains superhuman abilities due to the massive amount of radiation given off by the explosion, and a secret organization seeks to harness those abilities for its own evil purposes. Chelnov must battle and defeat the secret organization using his newfound abilities.

Gameplay:
The player controls Chelnov's movements with the 8-way joystick, and the 3 buttons to attack, jump, or turn around. Six types of weapons can be obtained during the game, and collecting power-ups can improve Chelnov's attack power, rapid-firing capability, attack range, or jumping height.

The game is a forced side-scrolling game where the screen continually scrolls to the right at a constant speed. Chelnov will continue to run with the screen even if the player lets go of the joystick. Though the player can move to the left or right of the scrolling screen by entering the corresponding direction on the joystick, it is impossible to stop or move backwards (Chelnov can turn backwards while jumping).

Battle Kid is very similar to "I Wanna Be the Guy", an indie freeware game for the PC, in terms of the design of the main character and the projectile weapon he possesses, the trial-and-error difficulty, and instant death mechanics of all enemies and hazards. However, the similarities end here as the actual gameplay and control is much more in the likeness of Mega Man games.
