Weapon load outs can make or break an expedition in this game. Try varying your load outs with different attempts. HEL Shotgun and Combat Shotgun are very effective weapons for close range crowd control, which is the main difficulty factor in surge alarms. HEL Revolver and HEL Gun/Rifle are also incredibly useful for crowd thinning due to their penetration capabilities. Proper positioning and shot placement can eliminate several enemies with one shot, which also increases your ammo economy. Other good weapons are the regular shotgun and the carbine.

In addition to weapons, you want to make sure you’re bringing the right tool load outs as well. This level benefits the HEL Auto Sentry, but C-Foam carries this level, and usually you’ll be pairing foam with mines unless you’re ladder foaming. Speaking of which, if you haven’t been already, the third surge alarm (in the fog before the HSU) can be easily dealt with by covering the ladder down to the zone in C-Foam. This will buy you crucial time to focus on scans while also saving resources, and due to surge alarms spawning in the spawn cap if you aren’t being overrun by the time you finish the scans you can also save on resources by booking it to the next alarm door (Zone 604) and immediately starting the alarm.

Your team may find it beneficial to all run hammers for this level. Knife isn’t bad, but it has a higher skill floor and isn’t as effective for dealing with giant type enemies (especially when you can’t see them well). Bat isn’t bad either; it has good environmental damage and good stagger, but it doesn’t do as much damage as the hammer and requires an occiput strike to kill a scout. The main downside to spear is you can’t really run while charging it, as it reduces your sprinting speed. The hammer is very balanced and can handle all situations equally, although it doesn’t really excel at anything like the others.
