Upper Anthill Room (2)

The battle starts with Alexia in her first form trying to take Claire down. You need to hit her as fast as you can with whatever weapon you have. If she gets you here, it's game over, plain and simple. Once you land enough hits, Claire will manage to escape, and Alexia will mutate into her second form.

Alexia's second form is pretty stationary, which is good, but she's massive and you'll have limited space to move. She'll attack using her tentacles and a swarm of smaller creatures. Your best bet is to keep moving around the open parts of the room and unload your most powerful weapons on her. The MAGNUM or SUBMACHINE GUNS are your best friends here – the faster you can shoot, the quicker she'll go down. You *can* shoot the smaller creatures she spawns to prevent them from bothering you, but honestly, it's a waste of ammo. Just focus your fire on Alexia II herself.

After you've done enough damage, Alexia will mutate again into her final, flying form. She's actually less threatening than her second form, but she'll be back to spewing fire. Your objective here is to grab the LINEAR LAUNCHER off the wall. This weapon works like the SNIPER RIFLE, so take your time to aim. One shot into Alexia should do it. She'll try to dodge, but thankfully, you have unlimited ammo for this final push.
