It's easy when you approach the stairs to the reichstag theirs a PTRS-41 on one of the buildings with a ladder and next to it there's a panzerschreck blast them then i think theirs a STG-44 and Gewehr. Pretty much hide out and stay far and keep shooting. After go and attack and a pillar will fall watch out it may hit you and you may die once it falls make sure your guns are all reloaded and shoot. When you get in you have to clear the bottom floor go all the way to the top of the building and you will find a PTRS shoot the germans with a flamethrower to kill more people with the explosion. After that it's easyNew question, open for details! How do you enter the reichgstad at the last mission on COD 5 xbox 360 NOT live?
after you take out the 88's try taking out the germans from a distance when you see a low number of enemies run up the stairs. hide behind stuff if more come out . make sure u reload and shoot a stone pillar will fall down. WATCH OUT!!!!!!!!!!!! move out the way a flamethrower will start attacking people , just don't get the way. after that just go up the top stairs with reznov. VOTE ME FOR BEST ANSWER!!!!!!!!!!
