The Conduit/Gameplay

This is a unique first person shooter set in Washington DC near the future. You're going to have to face a lot of aliens and "The Trust" which turned against you.

You play as Michael Ford, a secret agent that gets drawn into the alien invasion. You're going to learn not just go in and shoot aliens but to also interact with environments and use the ASE.

Here are the important factors to get started:
 * Strafing is important in dodging enemy fire. If you don't strafe, you could die easily and have to start over again.
 * Use cover. There could be places in which you get to take a breather so find places if the gun fight becomes too much for you.
 * Use crouch and jump. For crouching, just find cover with the right height to duck under enemy fire. For jumping, if you don't have cover, simply jump around encounters and also go to places you can't get to if you are just walking around the level.
 * Lock on target. With most games, you'll have a hard time trying to take down a moving enemy. Use it especially against bosses when you need jump and shoot around until you are certain the enemy passes away.
 * Zoom in and snipe. Some weapons have a sniping option. You can't change the range of the zoom but at least you get a more pinpoint accuracy. Use it not just in single player but multiplayer as well, if you can't take enemies up close, this is the alternative method which works well if you are free from enemies attacking you.

Features
There's a few unique features which is part of this game. The most unique feature is the ASE. You need it for a few factors: The other unique feature after level 3 which will help you through the game.
 * The door or section would be unlocked if you can find a number of yellow dots. Your ASE will alert you on nearby secrets so pay attention to it.
 * A puzzle in which you line up three arcs just to open a secret weapon area. For people new to the game, you should try out all the weapons and make good use of it.
 * Invisible messages will be hidden in every level. Also there's also data disks that needs to be collected. These play to the achievement. You'll unlock a cheat if you can find all the secrets in all levels.
 * The most important is the invisible bombs. You'll see a small red illusional light at first but your ASE will alert you that there's a bomb nearby.
 * Health regeneration helps you from dying if you can find a place to recover. It won't kick in until level 4 so you can take the time, taking down enemies unless there's a health item nearby or you can stop, wait for your health to heal then go into battle.
