detailed as much as possible method:
leftdodge on boat on left of spawn
leftdodge on the left base sorta
hammerup on the left ledge thingy
run toward the bouncy fans
go trigger attackers (more then 15 seconds have passed) by running over the "high way", i think the fastest spot to reach is like where the 2 textures meet on the roof
dodge over the fan and get boosted by it (when u land u should lose some hp but thats not against the rules
)
trigger the roof opening, just run down dont jump prolly saves a few ms
just run off the right part of the bridge near vent, (again a few ms gained instead of jumping or dodging down)
grab flak carefully (without getting the shock or any ammo)
head to the gate, (this part is quite tricky since to get it with only 1 primary fire u gotta line up close to it and right infront of it (not at an angle) and fire, but it blows and damages so the way i found to survive is lineup and fire/backdodge at the same time since the explosion is delayed a lil)
run and finish the map, if u get upclose by dodging down final obj only needs 1 primary flak
my best time...... 1:02
do I get a cookie?
