 * The last "missile turret" is very random and somewhat "intelligent" (moves in ways to avoid your shots), so care has to be taken here. The rest is fairly easy to execute. However, there is a small chance that weird things happen along the way. It can be enemies that spawn in slightly different locations and therefore being out of reach or a grenade that is tossed from one of the walls that can hit. This is rare though. The route shown here is made to be as safe as possible (it's possible to take a straighter route at the cost of some risk in some places).
 * The last boss takes 10 hits. Occasionally, the boss takes more grenades to destroy. Some observations of this behavior is described in the [[Ikari Warriors (NES)/any%25_deaths|death abuse route]].

+* The boss takes 5 hits (the hitbox is huge) and then you need to toss a grenade at the floor below the desk to reveal the exit. The staircase takes up two blocks and can be in one of several locations below the desk. The location is random and depends on the timer and player input leading up to that point. It doesn't appear to be possible to manipulate the location, but the underlying mechanism is not known. With the current knowledge, the best you can do is to throw one grenade from the left side to cover the possibility of the stairs being on the right side. If that doesn't work, turn around and toss a grenade to the left from the opposite side of the desk to cover the remaining possibilities. You should never need more than 2 grenades to cover all possibilities.

-The last boss takes 10 hits. Occasionally, the boss takes more grenades to destroy. It has been observed to take up to 20 hits. The reason for this is unknown, but by looking at the boss's memory address, some grenades don't register. Fortunately, the most common is 10 (and then 17). The other ones have only rarely been encountered.

 - Any blue soldiers that come close to the right side around the SS item will likely be a considerable threat. Many of the movement patterns of these soldiers will bring them in your way (including firing your way), so it's recommended to stop and take them out, even if it means a time loss.<br />
 - If the big tank doesn't shoot a grenade as you approach (rng), you can clear the bridge area ~40 frames faster, https://www.youtube.com/watch?v=NWnPupDT-gY. The risk of bad enemy patterns appears to be higher with this route though.<br />
-- It's possible to manipulate the tank into firing diagonally into the water instead of on the bridge. You need to pause briefly between the bridges. Overall, this approach would be a second faster or so since you don't have to wait for the explosion of the shell on the bridge. The pause has to be accurate down to the minimum time window of four frames and unfortunately appears to depend on player position and likely global variables (when the tank decides to shoot), which means this time save comes at comparatively high added risk.<br />

 - There are three guaranteed spawns at the beach. The pink soldier (harmless), a self-exploding guy (taken care of by the grenade) and another blue soldier. The latter will surface and hit you if you don't take it out with the gun as soon as it appears on screen. The problem in this area is instead the random blue soldiers. They both like to run into you and shoot you. There is no real guideline for how to deal with them. The firing and movement patterns in this video have been developed to take out many of the possible spawns, but are far from guaranteed to work in all cases.<br />
 - There is a knife on the left side of the first beach (see [[Ikari_Warriors/Level_Maps|Level Maps]]). It would make the rest of the section easier, but is a bit out of the way and would cost 3 seconds.<br />

 - The airstrike target plate after the first water section is problematic. With the route shown in this guide, the airstrike will often come from a position so far off that it will not hit the target before it's off-screen. The airstrike will then be "confused" and start following you. The best way to deal with this is to pause before the target plate is scrolled off-screen to ensure that the airstrike will not follow you. If that's not possible (or if the pause was too short), moving to the side will eventually make the airstrike to explode, but also costs time.<br />
 - The remaining parts are also very luck-based. There are several possibilities for random spawns that will end up firing at you. When possible, it's worth to go a little out of the way to take out potential threats. No matter what, the success rate will be very low (~10%?) of this whole section (end of the video).<br />
