General

Speed

the character walk on a constant speed regardless the direction (straight or diagonal). He only gets slow down while walking on high grass or water. It's clear that it's better to always walk and avoid those slow down zone. always moving up and shooting helps to have a longer range with the M-60, enemies move down faster

Enemie Spawn

The less enemies spawn, the easier it is to go through them. For that reason it's actually much better to not kill any enemies especially the one who doesn't move (e.g. flamethrower).

To avoid enemies it's better to stay on the far left or right, it's safer for unexpected fast coming bullet or running soldiers & motorcycle. Some cannot be avoid and shall be shot quickly, especially when they are very close or shoot fast (e.g. knife thrower)

Some scripted spawn can be annoying and can be skipped by killing some enemies a bit ealier.

End level screen

The end screen has a kill count, for example 16 for level 1. Enemies needs to be kill as soon as possible, better clear the screen before a 5th enemy tries to spawn, it would be skipped and time would be lost. for the last kill, it's optimal to be close to the gate to throw the bomb arrow right after.

🆕(june 2022) end screen gate can be destroyed earlier as described HERE. For each round (except round 6), after killing 16 enemies, the end screen gate can be destroyed with 16 shots (regular gun). it saves around 1 minute in total!

It's great to have some spawn on those end screen before the final scrolling up. Those enemies will be counted as regular end screen kill count and it helps to reach the min count faster.

there are some rocks or empty grenade launcher station that will protect you from bullet, very useful for safe runs but for faster strategy it's better to move around and kill asap

Grenades

There are everywhere, a real pain ahah! Staying to long in one section in the level would trigger a dropping bomb, one more reason to never stop. each end level screen has dropping bomb after a certain time and the next drop would be 4s or 3s after.

it's important to learn how to avoid them and practice, especially for the last boss. The strat is to make the bomb explode and then stay on a safe spot

Powerups

Not necessary to pick up, especially it's difficult to not die and it would need to be picked up again, especially the huts, there is a bit of a stop after shooting a bomb grenade. For some level it's better to get the super grenade powerup. The long range powerup would help for soome difficult part or for the end screen, but a bit risky since it requires to kill 21 enemies.

Round 1

the easiest one, a death here should be reset. keep the left the all time for safe strat or keep right for a bit faster by avoiding the grass.

For the end screen, there is a specific spot that allows to reach most spawn, except the to p right corner but moving a bit to the right does the job. Some enemies would despawn very quickly by walking out of the screen (top right), this is RNG

Round 2

First round with bridges and those has bomber spawn on it that would slow you down. Those bomber can be despawned by kill some enemies before. Those bridge are narrow and enemies will shoot at you, it's better to cross before they start shooting and kill the ones around that would shooot you.

The knife thrower are dangerous, they throw fast, it's safe if they are far enough but better to kill them (diagonally) after they throw the first knife.

Round 3

Round 4

Bridges are back, but this time there is 3 sets! same as round, try to clear the enemies around it and never stop to prevent receiving any shooting.

Because of the bridges, it's better to keep right

the end screen is same as round 2, the bomb spawn is earlier and faster

Round 5

maybe one of the hardest level but it's probably the less random stage because of the big number of scripted spawn: 67 (stage 4 is 33). Those blue snipper needs to be killed asap, they shoot fast!

The hard part is the end screen where there is no much place to hide and the spawns are everywhere. staying at the very top next to the gate is the only safe spot againts enemies bullet, but more risky for getting bomb

Round 6

it's better to take the Stinger Bomb powerup for the final boss, it gives 7 damage instead of 3 with regular bomb arrow! The power can be obtain by blowing up some big rocks on the way

the bouncing grenages are difficult, first one is tricky but can be despawn with the [?] item. It works when you get close during the explosion and run after. Walking diagonal might help a bit sometimes

for the final boss, start with the right part then the left, for more damage smash B1 & B2 at the same time. those 2 part can be destroyed before the first bouncing grenage
