TY the Tasmanian Tiger 2: Bush Rescue HD

Once you have completed enough missions you will be called back to Julius' lab. The final mission starts once you board the cargo plane. The final mission is fairly easy with some boss rush style mechanics thrown in. Hold down the button to charge your laser attack for the other mechs and the bosses. Patchy and Buster are easy to defeat with the laser. Boss Cass is also easy. when he is in the air the laser makes the fight a cake walk. The mech he summons takes damage when he slams the ground. In his final form with the lava surrounding him you just need to shoot him with the laser once he stops glowing. His final final form is just him running around the map so hit him to feel better and the game will end.
