How to unlock the No Offense achievement in Aliens Colonial Marines - Definitive Guide
I found it highly unlikely to get on a normal walkthrough, so it's best, if you really grind for it. It can be done on every level. I got it on "Fall of the Sulaco". After you short-circuited the doof of the controll-room, there is a section where you get attacked by two groups of three Xenos. Just wait till one of the Xenos comes charging at you and start your melee-Attack. If it's not working, just reload the checkpoint and retry. I got it on the third run...
Play up until you get to the cargo bay and the mission is to get to the control room. As soon as you enter the room, an alien will come up from the floor and pounce at you.
It will pounce at you every time. The checkpoint is literally through the door so if you fail then you can just try again
This is one of the harder trophies to obtain Offline. A Lurker is the Xenomorph that jumps at you and pins you to the ground whilst slashing at you. When you encounter one, try to keep your distance and learn how to interpret its movements. You can tell when a Lurker is about to pounce as it will be crawling on all four legs and will bow down before striking. You will have a very small time in which to react and melee it with the button. To perform this correctly, you need to physically hit it mid-pounce so that the animation stops and the Lurker gets knocked back. This will take a bit of practice and trial and error to get right. A good place to try for this is the Derelict Reclaimed level. There's a spot early on in the chapter where a Lurker will ambush you. Thanks to Terminator for providing the location.
If you're struggling however, there is a much easier way to earn this trophy Online. You can set up a Private game with two people and boost this trophy if you wish. To make it easier, have the Xenomorph player choose the Enraged Pounce ability, as this is considerably slower than a regular pounce and allows a greater window of reaction time for the human player to execute their melee.
Another achievement that is easily boosted in a private 1 vs. 1 Team Deathmatch. Have your friend spawn as a Lurker and meet at a open area (preferably a long hallway). This is about timing. The further away the Lurker is, the easier to react. Melee the lurker before it hits you with a pounce. The player controling the Lurker holds down and will see a trajectory of where they will pounce. Aim this at the person trying for the achievement and release when they're ready. May take a couple of tries. There's a few campaign locations for these, but perhaps the best is mission 4, at the very end. Before the final door is unlocked, you must kill 3 lurkers that spawn one at a time. Restart checkpoint if you can't get the timing for this achievement down before the 3rd one is killed.
