I believe I may have found a new trick for sword base that involves the target locator. What is this trick oh mighty crypto? Well boi, it allows you to fire off 4 shots from your target locator. What? Blasphemy! Don't believe me heres proof. SHOT 1 SHOT 2 SHOT 3 SHOT 4 All you need to do is use up the two shots before you get the gauss hog and hold onto the empty target locator. Once you get the checkpoint to receive the gauss hog your target locator will come back to two available shots. If you still doubt me then go try it out for yourself. I don't know if this helps or not but I sprinted past pretty much every enemy, activated the switches and then despawned all the enemies from the area you get the gauss hog before going back and acquiring that vehicle. Alright now before anyone flames me, Im just going to say that I haven't seen anyone talk about or post this before. If you have found out about then ok cool, don't be hatin'. also if you still don't beleive me: http://www.bungie.net/Stats/Reach/Screenshots.aspx?player=Crypocalypse
Going through the level while having it with you always gets you 4 shots. I remembering doing it the first time I played the level. It just recharges at some point. Not that much of a trick, really.
