alien arisen

long ago, aliens attacked Terra with odd technology, mechs piloted by aliens but these arent simple mechs that take an emp grenade to neutralise them they have a unique power each mech can generate a weapon from pure energy after the first attack another happend then another and humans realised this was going to continue but suddenly one alien pilot had chosen you, Alex to protect earths from these monsters but u cant defend a planet with 13 billion people all alone so human defence became stronger defence force: . sentinals controlled remotely, used to hold back enemies . fighter planes are like jets but bigger, and each holds 5 atomic stunners. The stunners are like atomic bombs, but they dont have a blast range. they're only built to break through the protective sheild now ur only goal is to defend the planet from these aliens. ur weapons are dual blades, and when u put them together they converge into one long sword due to ur history of taking down multiple enemies you were nicknamed the alien hunter but one day a two way street happens two alien mechs fighting together ready to eliminate u will u let them win or what? choose ur path
