Chapter 7: Respec
Isaac can re-spec his weapons, RIG, and stasis module at the start of the chapter. Note: Each item re-spec costs 5,000 CR.
Easy Stalker kills
If you are finding the Stalkers troublesome, the best weapon to use against them is the Line Gun. Try to find an area to back yourself into then simply wait and aim. They will eventually pop out and run at you. The Line Gun will easily dispose of them.
