Bridge Zig Zag


This walkthrough is based entirely on using and upgrading weapons first, and spending the excess on towers on the last couple of waves.

Caution: My guide requires one to be a decent sniper. If you can't get past wave 12 with only the sniper rifle, stop following this guide. Unless you are totally sick with aerial slows and grenades.

The format of this guide is based off the Mine Insane Walkthrough (Not the same person) to keep the flow.


  • Take Scatter Laser and Gattling Towers.
  • Learn to run through this maze backwards without getting stuck.
  • Use the maze shown on the right, it makes running backwards easier, yet has good enough turns to keep Chargers slowed.
  • You have to be quick with weapon changes (while running!)
  • Hitting weak spots is a requirement.
  • The basic rotation for weapons is use your freeze gun primary (slow), switch to sniper rifle and use all sniper bullets then switch to assault gun and use grenades or bullets without overheating it until either freeze gun or sniper rifle is ready.
  • start to slow enemies immediatly when they are within range; learn at which angle you need to fire your freeze gun slow to hit the first creeps that are far away. They spawn pretty far for your slow to hit, so take this time to snipe what you can.
  • Note that the freeze gun recharges very slowly, so it is possible to pull off 2 grenades from the assault before the freeze is ready, just wait for the charge to below 49% before firing the second grenade.
  • Note on Soakers: If you are not able to kill them as mentioned in the guide, do not switch to using the above rotation so soon, but spend additional time with the assault to build damage. Keep extending the time until you get it right.

wave 01Edit

16 Walkers
tactic: just shoot them in the face while running backwards infront of them
difficulty: very easy

wave 2Edit

5 Tanks
tactic: sniper their weak spots and slow them while the sniper is reloading 
difficulty: easy

wave 3Edit

36 Walkers
tactic: same as wave 1
difficulty: easy

wave 4Edit

18 Hoverers
tactic: sniper their weak spots (its on their backs) and slow them while the sniper is reloading
difficulty: easy

wave 5Edit

24 Chargers
tactic: sniper their weak spots and slow them while the sniper is reloading, try to get a few kills from the middle lane by standing on top of the first row of blocks and sniping them when they spawn.
difficulty: medium

wave 6Edit

40 Spore Pods
tactic: sniper their big heads, you should 1-hit them. They spawn pretty high up from the mountains, so keep a look out.
difficulty: easy

wave 7Edit

6 Big Walkers + 36 Walkers
tactic: use the rotation mentioned with grenades.
difficulty: easy/medium.

wave 8Edit

5 Tanks + 45 Runners
tactic: snipe tanks weakspot while slowing until runners catch up, then just slow + 1 or 2 grenade
until runners are dead. slow + snipe tanks again.
difficulty: easy

wave 9Edit

1 Soaker
tactic: Once within range, immediately slow and then proceed to punch holes in his glowly weakspot with the assault. Time your slows so you don't waste valuable time switching weapons and let the slow run its full duration. I slow every time my assault hits 30%. About 3/4 into the maze, use the rotation mentioned above instead. You might need the full maze to kill him. If he is extremely near your core, use your secondary freeze gun instead to stop him (long cooldown, but at that point it does not matter).
difficulty: medium/hard

wave 10Edit

36 Walkers + 18 Hoverers
tactic: sniper walkers once they spawn and ignore the hoverers. Once their within range of the freeze gun, apply the rotation with grenades until all walkers are dead, then go for the Hoverers. Your sniper should be one-hitting them in the weakspot.
difficulty: easy/medium

wave 11Edit

90 Runners
tactic: slow and grenade them to bits.
difficulty: extremely easy

wave 12Edit

15 Gliders
tactic: Snipe them the moment they appear, they have low health so a weakspot hit is not needed to kill them with your level 6 sniper. They move a lot, so wait for them to stablize their path if you are not good with sniping. It is even possible with a level 5 sniper if you can hit their weakspots.
difficulty: easy/medium

wave 13Edit

3 Soakers + 18 Hoverers
tactic: take early pot shots with the assault on the nearest soaker, then proceed to slow the entire group. Focusing on the nearest soaker. Once the hoverers step infront of the soaker you are targetting (you will notice many of your shots dealing 0 damage instead of nice red numbers), kill off the hoverers like in wave 4, then continue with the soakers like in wave 9 (They have lower health than the one in wave 9).
difficulty: hard

wave 14Edit

6 Big Walkers + 24 Chargers
tactic: same as wave 5. Kill walkers once chargers are dead. Take early snipes at the chargers instead of the walkers.
difficulty: easy/medium

wave 15Edit

36 Walkers + 50 Spore Pods
tactic: snipe the first few spore pods that spawn, until the 3 lanes of walkers meet, then proceed to kill them instead with snipes, grenades, and slows. Once dead, teleport to the bottom right televator and start sniping the pods, switching to assault to those that reach the core, don't bother with grenades unless you are really good with them. Attempt to lob the slows at the pods just behind the head of the pack if possible. 
difficulty: medium/hard

wave 16Edit

5 Tanks + 45 Runners
tactic: same as wave 8
difficulty: easy

wave 17Edit

5 Tanks + 3 Soakers
tactic: Start by sniping the tanks from far, wittling their health and hopefully killing a couple before the soakers get within range, then proceed like in wave 9 until they are all dead, then snipe the remaining tanks.
difficulty: medium/hard

wave 18Edit

18 Hoverers + 36 Walkers
tactic: same as wave 10
difficulty: easy/medium

wave 19Edit

50 Spore Pods + 15 Gliders
tactic: Ignore the gliders, your towers should be enough to kill them, focus on taking 1 snipe per spore pod, which will leave them with a tiny bit of health, then let the towers finish them off. Watch out for spore pods that float very high up and out of reach from the towers, press tab once in awhile to check if you need to teleport to your core and kill stragglers.
difficulty: medium/hard

wave 20Edit

5 Tanks + 6 Big Walkers
tactic: same as wave 2, just snipe and slow.
difficulty: easy

wave 21Edit

3 Soakers + 24 Chargers
tactic: same as wave 5, aim for the chargers then kill the soakers like in wave 17.
difficulty: medium/hard

wave 22Edit

36 Walkers + 45 Runners
tactic: same as wave 16.
difficulty: easy

wave 23Edit

18 Hoverers + 50 Spore Pods
tactic: same as wave 15, snipe the pods (don't finish them off, let your scatters do that) until the hoverers are in range, then proceed to snipe/slow hoverers until they are all dead then kill off the remaining spore pods.
difficulty: medium/hard

wave 24Edit

6 Big Walkers + 24 Chargers
tactic: same as wave 14, but their health is very thick.
difficulty: medium/hard

wave 25Edit

1 Soaker + 50 Spore Pods
tactic: same as wave 23, focus on the soaker like in wave 9 once its within range then back to the spores once its dead. You might let one spore pass, so keep trying until you get it right. 
difficulty: pretty hard
