Hard Corps: Uprising

Again, this achievement has to be done in Arcade Mode and not in Rising Mode.

You can't pick your upgraded character in this mode and will always start with 2 lifes and 3 continues. My advise is to take Bahamut since he has one health bar more than Krystal.

As of now I don't know if any cheat codes work. I tried the Konami Code on many screens and it didn't work.

Even the first level in this game is hard and you probably have to play it a few times, before you can finish it. Use the sprint button a lot. You can skip nearly every enemy on the screen.

Now a few tips for the bosses (Yeah, bossES. Even the first level has 4(!) boss fights and takes about 10-20 minutes depending on how many times you die)

Barrier:
You only have to kill the big one at the bottom. So start there and keep shooting. When it starts to glow, jump up on the plattform above you and kill the dude on the right side. After the laserbeam is gone, Drop down again. Rinse and repeat. I you manage to hold the Spreader, just stand right before beam so all three pellets hit. Also, spam the X button and don't hold it. You can shoot faster that way.

Robot (1st fight):
After you jumped on the motorcycle stay right. You can't shoot to your left without moving in that direction. So start on the right and drive towards the enemy before he starts shooting. Now just jump over every pellet and try to hit him while in the air. After a while he stops doing that and tries to ram you. Stay on the far right so he doesn't hit you. Now just keep shooting while avoiding his attacks. He always starts with jumping at you. Get to the far left when he is in the air and jump over him immediatly after the lands. For the other attacks you can just stand on the right side. Everytime he is on the far left, keep shooting him. His last attack is the flame thrower, which is easy to avoid. As soon as it flashes, doublejump and airdash to the right. Another tip for better movement. You can't dash on the vehicle, but you can still air dash.

At the end of the fight, you will jump over a cliff. When the JUMP appears, double jump to the right and air dash to land on the other side.

Metalworm:
Right before the fight you will get a machine gun. Try to keep it. If you lose it in the fight, you have to destroy one of the little spines. They drop medals but also a machinegun sometimes. This will make the fight and also the next one much easier. There are only two points where you have to stand. If the worm is in the middle, stand on the far left side. And when he's on the left, stay in the middle. Keep in mind that you have to jump. You can run over the sand with your dash.

The only two exceptions for the rules above are if he does a certain attack. If he is in the middle at immediatly jumps at you, sprint to the right and don't stand in the middle. He will repeat the jumpf 4 times. You can walk between the gaps and can shoot the spines, but I find it more difficult and I only do it, if I loose the machine gung before. The other one is, when he is in the middle at shoots fire. You can try being cool and avoid the fireballs while jumping or you can just stand in the middle part between the boss and the left screen. The balls land always in the same places. When he does this on the laft, just stand in the middle start and jump while shooting. The balls never hit you.

For the rest of the fight, just stand and jump at told positions and avoid the attacks. The little worms can quickly be killed and the blue arrows are easy to jump over. Just keep at it and he will die, opening the way to jet ANOTHER boss fight.

Robot (2nd fight):
So this bastard tries his luck again and starts in the second phase of the last fight. So repeat your tactic until his health bar is half way down. Then the upper part starts jumping from one side to the other. Start in the middle and keep shooting. After his second jump drive under him to the right and repeatt for the second time. Now the bottom part will jump in the air. Quickly get to the left and jump as soon as possible over the two robots with a double jump plus air dash. This has to be done quick, so you have enough time to jump over the upper part, which sprints to the right. Then the whole thing starts over again until you beat his ass.

BUT WAIT: After this point there is a last JUMP-section where I died the first time. And you knwo what? You have to start over right before the worm-boss. So to keep you from this experience, jump when you are right befor the helicopter and use the double jump to correct your movement. You have to hit the metal bar under it or else you'll fall and DIE.

Hope this helps. If only the rest of the game were this "easy".
