Arcades are pretty much dead. Well technically, that isn't exactly truthful. But it is on it's very last legs. Seems as though the only thing keeping the arcades alive anymore are rhythm based games such as Dance Dance Revolution and fighting games (and to for a different take, the Xbox Live Arcade has emulated the arcade seemed through online services). It's pretty sad that only a few years ago, arcades were not only everywhere, but the leading part of innovation in the video game market.
Nowadays, it seems as though even arcade games are straying from easy pick up and play mechanics that they themselves have established. Fighting games have become so involved that any newbie trying to join in will become totally lost in the sea of moves of combos and different counter attack movements. Others feel intimated by games like DDR and In the Groove only because the people who usually play them in public are the crazy hardcore types that can play ten footers with x8 speed mirror dark without ever looking at the screen. To most, that doesn't seem very user friendly.
There was a time where games were simple in concept and the only requirement was to eradicate all enemies on the screen. Shooters and beat-em ups were everywhere, but then they became few and far between until it became rare to see a release of them in arcades. Enter Capcom and Psikyo's Cannon Spike released in 2000. From the minds of Strikers 1945 series and the Gunbird series comes a game of Capcom fan service goodness and genre blending of shoot-em ups and beat-em ups. Funny how Capcom trusted another company with a lot of their precious properties, although Psikyo was experienced anyway as they handled Gunbird 2 which had a cameo of Morrigan from Darkstalkers. The game main characters are comprised of Capcom characters, some mainstream and others being rather obscure.
Cammy is a part of the crime organization of Shadowloo (led by M. Bison). She is sent in to stop the terrorist that have suddenly risen in the world. It's weird that a crime organization is that concerned about terrorist, but whatever. After being in some trouble, she is joined by Charlie to help out. Cammy is from the Super Street Fighter II game and her Street Fighter Alpha uniform is hidden in the game. Just like Charlie, a lot of her moves are based on her fighting game appearances (specifically Cannon Drill and Cannon Spike).
Armed with his gunlance "Excaliber", Arthur is the ultimate one man army. He is here to protect and assist Simone (what's up with all the girls needing help in this game?). Hard to believe due to the extreme make over, but Arthur is actually from the Ghost 'n Goblins series. He's the heaviest character, but it turns out it's a giant robotic suit with little Arthur controlling it inside.
Do you really need a description on who Mega Man is? Well, he's the human-like robot created by Dr. Light to help protect the world from evil and make living on Earth peaceful for humans and robots alike. He's from the Mega Man series. His Mega Buster and Tornado Hold are taken right from his games. Also of note, Capcom mistakenly put Mega Man Volnut's picture (from Mega Man Legends) in the instruction manual, when it is actually the original Mega Man in the game.
An overly cocky bastard, Shiba is a pro skateboarder who almost won the world title if it wasn't for him getting involved with the terrorists' conflict. He's now in an assault team to counter attack the terrorist. Shiba is actually from Capcom's Three Wonders as the player two character, although his name in that game was Siva (a different transliteration of the same name in Japanese.) His avatar/option is there to accompany him, although he only comes out during Shiba's special attack.
Charlie / Nash
From the Street Fighter Alpha series, he joins the team from the US army to assist Cammy on a mission. A lot of his moves are actually based off his fighting style from Alpha which in turn is a copy of Guile's attacks (specifically Sonic Boom and Somersault Kick).
A cyborg with superhuman strength, She works along with Arthur to complete her mission. Simone seems to be based off of Lt. Linn Kurosawa from Capcom's Alien Vs. Predator arcade game. Early sketches look as though she had at one point the head of Rouge from Capcom's Power Stone series.
B.B. Hood / Bulleta
A very dark individual, B.B. Hood is a bounty hunter only looking for treasures. Capcom describes her as, "Though she is human, she has the same dark hearts as the Darkstalkers." On a side note, B.B. Hood rides an adorable scooter instead of being on roller blades. She is from Darkstalkers 3 and much like the other fighters in this game, some of her moves are loosely based off her fighting version (specifically Cheer of Fire and Apple For You). Her faithful dog Harry is no where to be found however.
One of the main villains in the game, you will encounter him twice (once as Fallen Balrog and again later as Revenger Balrog). Appears as an extremely goth version of Balrog (odd how they never changed his name to Vega in the localized version) from the Street Fighter II game except that he has two claws. His one attack, the Sky High Claw, is taken right from the fighting game. He can throw knives out of his claws.
Cat Lady Beauty
A gorgeous assassin with cat ears formed from her own hair, she wields a rather large rifle and accompanied by two wolves. Once you initially defeat her, she pulls an Altered Beast and transforms into some bizarre cat/bat/beast thing that can shoot random bullets from I'm guessing her mouth.
Another main villain, you will encounter him twice as well; first as the Flying Fortress with him acting like Dr. Robotinik/Eggman and shooting you from a hovering device and second as "Revenger" where he amasses huge gatling guns on his arms. Extremely massive.
The leader of the terrorist groups, he's really agile for a guy who needs and uses a crutch. Once his suits of armor are destroyed, he'll make three clones of himself and you must find the correct one out of the four to actually inflict any damage.
As you can see from the character line up, the game is teeming with Capcom fan service, but that isn't all. The Unholy Dwelling is straight out of a Resident Evil game, right down to the zombie dogs attacking you. Some of the towns, such as The Occupied Town and the Perished Town, seemed to be based off some Street Fighter and/or Final Fight locales. And mentioned before, some of the characters have their trademark moves as their attacks.
The interesting thing about the game is its setup. It can be easily described as a shoot em up mixed with Contra for good measure. It's over head, one screen look gives it a Power Stone feel to it. While not creative by any means, it gets the job done by being a fast paced shooter. And it's rather hard too. Not so much because of the enemies AI (which at times you wonder if it even exist) but for the sheer amount of fire power that they have and a total lack of reaction to your attacks.
Being an arcade game, there typically isn't a story and you'd be half right. The story is some kind of nonsensical mess about terrorist robots running rampant in the world and it's up to an "Anti-Robot Special Force" equipped with motor boots to destroy this evil menace. It's a bit weird that they randomly name your group the Anti-Robot Special Force, yet in the instructional manual each characters biography makes it appear as though they are working alone or affiliated with a different group. The actual game makes no mention of this, as you are immediately thrusted into the game ready and raring to battle.
Cannon Spike keeps it pretty simple with it's one and only objective: destroy everything that moves. Each button has a specific attack. Normal and heavy attacks take a cue from beat-em ups such as Final Fight for fighting enemies up close with physical attacks (which are specific to each character). Since each character is loaded with a gun, each character can also shoot down opponents from afar with a rapid shot or use heavy shots that are also specific to each character. Using your gun and physical attacks effectively is key in this game. The rapid shot is really weak and the Heavy Shots have way too much lag afterwards, so using physical attacks aggressively is actually a good strategy (some of the character's physical attacks are actually stronger than their heavy shot counterpart!). Last but not least, are the special attacks which can only be used if you have at least one special item.
The special attacks usually end up with some very impressive explosions and most enemies being completely fried. You always start out with five in stock and there are at least one special items to perform the special attack in each stage so you can use them frequently although it's best to use them during boss battles or when the pressure is too much. All this shooting and fighting wouldn't be tedious with out a targeting system, and Cannon Spike has one albeit a bad one. You can lock on to enemies so you can skate around and shoot them to your hearts content. The only problem is that the lock on only last for four seconds, so after that you have to either relock on or you're going to be shooting sporadically with out realizing it.
The game is set up much like Alien Soldier, in where that the game is pretty much one boss battle after another. At the start of each stage you have to battle waves of terrorist which usually consist of either humans with weapons, robots, or robots with weapons. All enemies are typically the same, with being able to usually just shoot out tiny bullets or land a punch if they're close enough. Once you have defeated every enemy, a midboss accompanied by with more enemies comes along to wreak more havoc. The midbosses tend to be much more massive although sometimes not so much and they range from a helicopter to a zombie gorilla. Once you defeat this wave, the actually boss of the level will attack you with the possibility of having minions with him/her. These bosses are the games challenge as they tend to shoot many bullets for you to avoid much like a shmups. There are a few instances where they will shoot at you that is reminiscent of a bullet hell feeling, as with many Psikyo games, with all the projectiles coming in at you. It sometimes weird however when some opponents will fire at you even though they don't have a weapon on them such as Cat Lady Beauty's second form or Fallen Balrog's five way knife throw from his claws.
Once you beat the game, you are given some gorgeous artwork of character specific endings. Not only are there specific character endings for the one player mode, but two player mode has specific endings as well. The funniest one I've seen is after Cammy and Shiba complete their mission, Cammy makes Shiba become her bitch and go shopping for herself. Beat the game once and you are treated with gallery mode to view official artwork and sketches for the game.
At a technical stand point, the game doesn't fair too well. As an arcade game, it looks fine. But this game isn't looking too sharp on the Dreamcast. I will commend the artist for the game however, as the art is really top notch and the make overs for the characters are really well done. The music...ugh. The music is terrible to listen to and some of the songs don't start up right away so you're left with silence for about three seconds into a fight. The only tracks that sound even remotely decent is the Uninhabited Station area and the Geofort Entrance. One level, which takes place in an abandoned mine, has music ripped straight out of Indiana Jones. The only voice acting are the yells and such whenever you pick up items - they're alright but highly repetitive.
The only real complaint about this game is that it's really short. And I mean short like it will take you literally ten to fifteen minutes to beat this game. However short the game may be, it's one of those games that is always good to pop in once and awhile just to blow up terrorist robots.
