Map20: Central City (Prodoomer)

Central City is the first of several urban maps, consisting of locales such as tenements, a plaza, and a grocery store. Snipers are everywhere, and more will teleport in as you progress through the level. This is also the map where you will acquire the Wall Jump ability.

If you want to get the achievement "Yes I'm Invincible," keep your armor topped off throughout the level, since armor damage does not count. Kill any nailborgs first, because their projectiles are armor piercing and will directly damage your health. The hardest part is the boss encounter, described below.

Average Payout: 6,700 credits

Secrets
1. In the central plaza, rocket jump on top of the west building in the southwest corner (the third building on the left where the mancubi were positioned). Crouch and go through a false wall to a teleporter. Destroy the sentry turret and collect the backpacks.

2. Through the blue door, search the south wall on your right for a secret elevator. Destroy the sentry turret and collect the ammo.

3. Once you get into the ductwork behind the eastern restroom, you'll have to wall jump up to an area with imps and hellions. Look at the south side of the shaft you just climbed for a false wall, stained with green. Crouch and drop in, and follow it to a secret. You'll have to wall jump back out.

4. Do the same on the other side.

5. In the room where you fight the minibosses and get the purple keycard, jump over the chair and walk through the false wall to get a grenade launcher.

Rings
37 Take the west road from the central plaza all the way to the end and enter the alley on your left. Jump on top of the trashcan and wall jump all the way to the top through a false wall to the east. The ring is right here.

38 This ring appears in the fountain in the middle of the plaza, but it's not available from the start. Check the fountain later after you defeat the two minibosses and get the purple keycard.

Easter Egg
In the vents behind the restrooms, there are dual fans to the north. Check your automap and you'll see a passage that extends beyond the fans, but the fans are impassable. You'll have to fire a Remote Control rocket through the fans and down, then turn it up sharply, then level it off to strike a red shootable switch in the back. To see what this switch did, return to the start of the level where the south doors are now open.

Boss Strategy
The first thing to know about this encounter is the Roadkiller can't be damaged in any way. You have to outrun it, but that's not easy because it moves twice as fast as you and can teleport around. There are also rows of kamikazes at every turn of the road, and they can use the same teleportation zones to close in on you. The path has no ledges or alleys, so there's no way to catch a break and hide from the Roadkiller.

You will need to make use of several abilities. Turbo is necessary, but may not be enough, even if you strafe-run. If you are lvl 26 you should use Invisibility and run away without firing any weapons that could give up your position, and if you are lvl 27, Clock Freeze makes this part very easy. If you have neither of those, cast Iron Prison on the Roadkiller and hope for the best.

When you leap across the fissure at the end of the road, the Roadkiller will automatically be destroyed, even if it doesn't fall into the chasm. Any kamikazes still chasing you will also plummet into the pit and die. You get 100 XP for winning the race.
