cpm1a is a rather sympathetic and extremely arcade map which is a remake of q3jdm8a. There are 2 Rockets, 1 Shaft, 1 Railgun etc, and only 2 Yellow Armors, which doesn’t allow any player to pick up too much. A player usually runs with 100 Armor points, this allowing the opponent to frag him with two rockets if the situation is favorable. So it’s important to improve your aim before a duel on cpm1a and learn to fire with maximum accuracy.
The mail weapon at cpm1a is the Rocket which can be used in all situations. Next comes Shaft, as the level’s rather small size lets you reach the opponent with it almost from any position. And the third is Railgun as there are momets in the game when there is nothing to hit the enemy with, but the Railgun. Here are the examples of such situations:
It can be difficult sometimes to reach the opponent on the lower Yellow Armor or, on the contrary, if you are at the GL and the enemy is at the upper Armor. This is when Railgun is indispensable.
Usually every player spawning for the first time gets a Rocket and an Armor, so you have to try to get the Shaft first, then Railgun. After that you can be sure there`ll be no situation when you and your enemy are at the opposite sides of the map, and you have no weapon, but the Rocket.
If you are sure the enemy has only Rocket, you can try to catch him while he’s taking Shaft or Railgun. Anyway, you must have enough armor points as the opponent might have good reaction and your actions will turn against you.
Even if you are armed, and you’ve just killed your opponent , it often happens that he takes the Rocket, attacks and kills you, so try to listen carefully to his respawns and grab all the armors. Don’t forget to fire control rockets aiming for edges, corners etc. Also you have to learn how to move on the level ideally with max speed possible so you wouldn’t need to think how to jump over at some place, but concentrate only on the enemy. Right after killing him, fire with the Rocket to the nearest respawn – you can do an Excellent at cpm1a very often, just keep your eyes open:
If you killed the enemy at the jumppad next to shards or at the upper armor, shoot the nearest respwan – there’s a big probability that the opponent will reappear there.
Nevertheless, if the enemy reappeared somewhere else, but he hasn’t taken the Rocket yet, try to catch him while taking the upper or the lower one. You shouldn’t show yourself till the last moment...
If the enemy respawned on the lower armor, catch him while taking the Rocket, hiding behind a pillar. If he’s somewhere else on the level, listen carefully, and as soon as you hear a jump down shoot the Rocket. The opponent will be almost for sure shot and seriously wounded.
If you don’t know where the enemy is for the moment, try to catch him at one of jumppads.
Actually, these are all main nuances in duels at cpm1a , the most important moments remaining: Rocket, Shaft and Railgun firing accuracy, as well as your displacement on the level. Learn how to do all kinds of jumps, like those to the big medpack and back, from the upper teleport to the armor on the left etc. If you need to keep the score, you can hide behind teleports, better with a Rocket:
Don`t forget that rockets can be fired through any part of the teleport.
