In the last difficulty:that's the best training.The sum of my IGT is 2h53'58.You can always be aggresive,even in this mode.

The barricade of shield:they are not immune to grenade,so it's an ordinary mass fight,you can do charged shot+G on the reinforcement.Before that,you can buy the faster reload and the inferior shotgun that can still headshot every previous ennemies.

Grand lancer:a charged shot will stun him before opening the door.

Reload the checkpoint before. Go to the top of the building on his right,you may miss it but it's possible.No reinforcement will come,you'll find a rocket,use it on the big robot before the spider(you can hit her weakspot from far).

Iron Raptor:aim at the targets behind,use the bazooka first,the secret is to stay in the building and to stepback while locking on and to shot through the door on right,the missille will do the turn,it can really bypass every thing,réapproach before redoing it.Outside,step toward the munition while shooting,ask for help againts the attackers,maybe you'll need to destroy one of his missille,only one.

Cylindric robots:run in circle and release the CS at the right time so you get 2 of them each time,awesome locking.

The weapon of Rachel and Faye are very strong and upgradable,can destroy ennemies without headshot or boss with extra CS from the shops.Headshots depends of the moment where you zoom:nor too far nor too close,a short passage everytime,a mouse isn't avantaged.

Gorilla:a few levels in precision help objectively,remember that you can always move while aiming and shooting. Recover all your CS in the shop close to the ladder. Ask Shindo to give munitions while you shot and stun him"shut up slave",press the roll button without direction,i remember some reinforcement on right and some red robots destroyed by an explosive bottle.

Crabe:i remember that it begin with a backroll+stepback but he take the close crate if you're too far.Only one CS,attack with the sniper,a strange thing is that it's damages don't combine to those of your rifle.How to dodge the toss:move on a direction,roll to the other.

Tsar Runner:snipe the previous ground ennemies.Always shot the closest part but the head should be destroyed in last,his missilles are easier to destroy when they are closer,it can blow up flyers.

The 2 artilleries:use the jamming grenades from the shop in front,the smaller ennemies will attack them,order the allies to attack.You don't need to destroy the very first,just the ennemies in front,welcome the reinforcement with rockets.

Kill the shinobis by shooting their legs.

Médusa:begin with 2 rockets.Before climbing,buy the sniper and upgrade it.Wait to see if she double turn.

Skelet:use the shotgun of Rachel, the rifle to remove the protection and for the CS (faster after reload).You won't need the alarms.

Fauver:walk on right,remove his plating with sticky grenades,CS and very close shotgun,he's too fragile for you as well.

Final boss:destroy the feet of the previous ennemies.Use the CS when his very first grenades exist.You should have the shotgun and sticky grenades,every explosives can stun him,use all the remote ones at once,big rocket launcher and CS in last.
