6. Red Faction 2 PS2 / Chapter 8 Inside the Nano Base / Boss: Repta
1Repta is a tough opponent since you have to fight him two times. The first time he has the multiple grenade launcher equipped. Always have cover in between him and keep your distance. Use the Rocket Launcher and when it runs out, the good old grenade launcher you got at the start of the game. Watch out for all the electricity flowing around as they damage Alias. Once he's done don't forget to pick up his multiple grenade launcher, it will be useful for the final boss in the future. 2nd time Alias will be on an armored suit so unleash firepower whenever Repta appears while getting rid of his helpers. Once his HP is below 50%, he'll run away and you'll have to get out of the armored suit to finish the rest. Use whatever weapons you have just know that he has a rifle or machine gun equipped while he can shock you, which is annoying.
