Always send Mooch up into vents you can't reach, check up on the hanging lights in rooms, try not to skip any areas. You need to be very thorough and search everywhere. This is one of the hardest trophies in the game. If for some reason you missed the 80% accuracy trophy in your first playthrough you will need to get it in this playthrough, and since you will be rushing through it may be more difficult to take your time and aim on enemies carefully, so do try to be extra careful for that trophy on your first playthrough. You will get all the guns by getting the Gold Data Discs which can't be missed, but you will probably miss a good bit of the Silver Data Discs, however that shouldn't be a problem because you don't really need all the upgrades they provide in this playthrough. It may seem more difficult to go through that fast on the hardest difficulty, but you will know what needs to be done in every area since you have already played through once. Start your second playthrough on Special Agent difficulty and you will need to go for the ' Beating the game in under 8 hours' trophy. If done correctly and you didn't miss any of the important trophies (like Master Agent, if you missed Master Agent you will have to play the game 3 times), on your second playthrough you should only need to get Distinguished Service Medal and G-Force Rapid Response Agent trophies, plus any weapon kill trophies, if you missed any. So since you are taking your time so much on this first playthrough, it makes sense to just get all these out of the way so you don't need to worry about them on your second playthrough.

If you do miss any of the 100, the kills will carry over to your second playthrough, but remember you will be rushing through on your second playthrough and the enemies will be harder on the hardest difficulty. Remember to let the computers that spit out little spider monsters keep spitting them out before you kill the computer as you can get a lot of kills on the spiders. Be sure you buy weapons as soon as they are available in the game so you can get the 100 kills with them and then move on to new weapons as soon as possible or back to a weapon you feel more comfortable with so you can more easily get the 80% accuracy trophy.

None of them are overly difficult, just try to use them often enough and you will usually get ammo for the weapon you are using out of crates/boxes (do not buy ammo with your chips as this will most likely prevent you from having enough chips for the Master Agent trophy).

You should also try to get all the ' 100 Kills with Weapons' trophies on this first playthrough. On your first playthrough play on either Easy or Normal, take your time and go for the Master Agent trophy, collect all 50 Silver Data Discs, and the 80% accuracy trophy. You're going to have to play through the game twice, so you need to focus on a few trophies each time.
