个人童年接触到的第一款单机游戏，也是第一款通关的单机游戏，虽然很喜欢，但是刷成就的话，明显没有多周目的想法和欲望，所以这里介绍的基本是通关一次主线10个关卡后，剩余有难度的成就刷出来的说明。如果大家有更好的方法或者想法，欢迎留言交流。

Please leave a message if you have better ideas or suggestion. I will be appreciated.

玩到第9关，使用女性角色（天赋拥有更好的移动速度和精准度），3个血量芯片，3个速度芯片，3个精准度芯片，红色护甲，医疗包，岩浆迷你机关枪和对应的子弹500发。如果你已经通关主线并不想再次玩到第9关，请参考本指南最后一章：如何选择关卡。

这些条件不是必须的，但是拥有这些条件可以帮助更快速地拿到摧毁箱子以及摧毁圆筒炸弹的成就。

按照下面的路线行走，并使用熔岩机关枪摧毁你看到的箱子和圆筒炸弹，中途有2个增加100血的道具和一个红色护甲作为补给，保持移动并且保持开火，摧毁完毕按下esc退出到主菜单并再次选择CONTINUE继续游戏，反复刷即可。

大概50秒到60秒完成一局，每一局总计摧毁101个箱子和65个圆筒炸弹。

Play to the 9th level. Use female characters (talent has better movement speed and accuracy), 3 health implants, 3 speed implants, 3 accuracy implants, red armor, rescue bug, magma minigun and 500 rounds of magma minigun bullets. If you have already cleared the all levels and do not want to play the 9th level again. please refer to the last chapter of this guide: How to choose the level.

These conditions are not required, but possessing these conditions can help you get the achievements of destroy crates and destroy barrels.

Follow the route below. Use magma minigun to destroy the crates and barrels you see. There are 2 MEGAHEALH and a RED ARMOR as supplies in the middle. Keep moving and keep firing. After destroying, press esc to exit to the main menu and select CONTINUE again to continue the game.

Approximately 50 seconds to 60 seconds to complete a game, each in total destroyed 101 crates and 65 barrels.

1. 女性角色：拥有良好的移动速度和精准度天赋(精准度可增加枪械伤害)
2. 速度芯片：增加你的移动速度获得1百万分最重要的道具，拥有3个即可大大增加生存可能性
3. 血量芯片：增加角色血量上限
4. 超级医疗：能突破血量上限，最多额外增加100血
5. 医疗包：当角色受到致命一击时，血量回复至满状态，并启用无敌护盾3秒
6. 无敌护盾：15秒内角色处于无敌状态
7. 红色护甲：给予300点护甲，受伤时护甲为你承担90%的伤害(绿色50%，黄色70%)。
8. 全屏冰冻：给与全屏怪物大量冰冻伤害
9. 全屏炸弹：给与全屏怪物大量爆炸伤害

一定要保持移动，使用火力最强劲的武器，保证自己前进的路不被异形挡住，围绕建筑在周围绕圈来阻挡大部分异形的火力，不要舍不得弹药，尽量把异形打死在自己的必经之路上来给与自己更多的道具获取。

1百万分在简单难度几乎要击杀全部的异形，在困难难度只用击杀到倒数第二波，也就是在全屏都是蓝色的怪物出来之前即可获得，同时也需要更加良好的操作和生存能力。如果简单难度觉得不容易达成，不妨尝试困难难度。

1. Female characters. Female have good moving speed and accuracy talent.
2. Speed implant. Speed implant increase your moving speed. get 1 million points of the most important item. 3 can greatly increase the survival possibility.
3. Health implant. Health implant increase the upper limit of the blood volume of the role.
4. Megahealth. It can break the upper limit of health volume and add up to 100 extra health.
5. Rescue bug. When the character is in a state of sudden death, the health volume returns to the full state, and the invincible shield is enabled 3 seconds.
6. Invulnerablity. The character is invincible in 15 seconds.
7. Red armor. Give 300 defenses. And reduce damage by 90%.
8. Freeze enemy. Gives a full screen monster a lot of frozen damage.
9. Bomb. Gives a full screen monster a massive explosion damage.

Be sure to keep moving. Use the most powerful weapons, and ensure that the road ahead is not blocked by the aliens. Move around the building to block most of the alien fire. Don't save bullets. Try to kill the aliens in your own way to get more props.

1 million points in the simple difficulty almost to kill all the aliens, in the hard difficulty only to kill to the penultimate wave. That is before the full screen blue monster comes out. But also needs a better Operation and survivability. If the difficulty is not easy to achieve, try hard difficulty.

Easy difficult. All clear.

困难难度，倒数第二波：
Hard difficult. Penultimate wave.
