Use bots on Arms Race and die to the same enemy four times in a row.
Easy "Conservationist" Trophy
Only use your knife during an Arms Race game. Note: Be careful not to set up kills for the other team. You now must get two kills with each gun before switching. Focus on prioritizing your shots with headshots. Do not spray your shots. You also must win the match. If you cannot win a normal Arms Race match, play offline with easy bots.
Easy "Defuse This!" Trophy
This can be earned by killing the player who defused the bomb, even after he defuses it during the final seconds of the round.
Easy "First Things First" Trophy
Play offline with bots under the Easy difficulty setting. Choose the Bank map because it is open. Chose the counter-terrorist faction and run directly ahead to the front of the bank, killing all the terrorists you encounter. Shoot any of them going into the bank vault because that is the bombsite. You can plant the bomb anywhere behind the counter. If you are quick enough, you can get all five kills before your friendly bots get any. Note: You will get new guns and grenades on each round.
Easy "Friendly Firearms" Trophy
Use Terrorist only guns to kill Counter-Terrorists and vice versa. Terrorist only weapons are the Glock, Tec-9, Sawed Off Shotgun, Mac-10, Galil, AK-47, SG 553, G3SG1, and Molotovs. Counter-Terrorist only weapons are the P2000, Five-SeveN, MAG-7, MP9, FAMAS, M4A4, AUG, SCAR-20, and Incendiary Grenades. It will be easier to find AK47s and M4A4s.
Easy "Killanthropist" Trophy
Drop the bomb in de_map or Demolition. Keep buying primary weapons during the warm-up period for a match. You will toss the weapon you currently have equipped on the ground, which is usually picked up by players who have not purchased a weapon or have just spawned in. Secondaries will not work because the other players must manually switch to it from their starter pistol. Purchasing cheap primaries like the MP7 allows you to get the most out of your money.
Easy "Magic Bullet" Trophy
Start an offline game with bots. Get a weapon such as the AK, FAMAS, G3, Scar or equivalent rifle. Expend all your ammunition except for a single round. Note: Save two rounds if using a sub machinegun or pistol because a helmet will have a single bullet protection from low damage weapon. Wait for a bot to stand still at medium or close range, then get a headshot.
Easy "Target Secured" Trophy
Play offline with bots under the Easy difficulty setting. Choose the Bank map because it is open. Choose the terrorist faction. You will automatically spawn with the bomb. Instead of planting it, take it with you up the first ladder, then go to the left roof and kill all the counter-terrorist players that you see on the street. Drop down and kill the rest of them, who still should be nearby. With luck, your friendly bots will not have killed anyone before you. If not, try again. Note: You will get new guns and grenades on each round.
