You arrive at the tower, you notice you haven't spawned in the normal spot and you have your gun with you too. This would be players first experience in a 'Defense' event at the tower. Enemies would spawn in where guardians would normally spawn and guardians would spawn before the IB Door. You'd have to stop the enemies from advancing and if they reach a certain destination (Maybe everyone gets sent to orbit if they reach it??) Also, those saying what if they don't want to fight; you can go to the reef or just avoid the fight. Rewards would be given to everyone after killing all the enemies. This would be really cool if [b][u]EVERYONE[/u][/b] in the tower pitched in on this and helped slay whatever tries to breach the tower. Instead of us going to the enemies, for once they would try attacking us. Showing that the enemy is capable of attacking too. I would assume that a notice would appear on everyone's screen at the start of this 'Defense' and would last till all of the enemies are killed or before they reach a destination at the tower on each server. Leave feedback and let's hope Bungie sees this!
