There are 8 levels in Contra. The last level is similar to a biochemical monster with many glasses. I just finished it yesterday. The boss of the first level was an airplane, with many special forces jumping down from it. I aimed the S-bomb at the hatch, and it was easy to pass the level.
I think in terms of game balance, the first generation is better than the second generation. The difficulty of each level in the first generation is moderate, but it is normal for the levels to be difficult, especially levels 3, 4, 6, and 8. The second generation sent too many troops to each level, which made it more difficult, but beating the BOSS was actually very easy. Perhaps due to the special effects of the game, the interface is better than the first generation. Use the S gun to shoot the red star at the level and you will pass the level immediately. Therefore, the balance is not as good as the first generation.
In the second level, I like to kill the main gunner from the top. It is easier to pass the level this way. Have you tried it? But it's best not to touch the electricity, as it will freeze you.
There are two bosses in the third level
The one in the front looks like a crab. I like to jump on it to fight. The one in the back is a smart turret. Just aim at the middle and fire.
The boss of the fourth level
This is called a laser bar weapon, and you can easily get through it as long as you dodge regularly.
Level 5 Skeleton Spaceship
In this level, just aim at the middle and fire, but be careful about spitting out the minions.
In the fifth level, the boss I passed looked a bit fierce, and he also had dragons coming out of his hands. We quickly opened fire to solve it.
The seventh level,
The boss in this level is mainly aimed at the middle. Hanging in one of the positions can hit the eyes. I think it is best to use S. Use it to blast a few times, and the boss will spray bombs. When you find that the boss's head turns red, it means that it is almost over. .
Level 8
I remember that there was a time when the boss couldn't use any attack items and just stared there. Blink, blink! Have you encountered it?
