Ascension is an exceptional map. First of all, there are only pairs of gold crates to blow up here. Secondly, except the one infantry transport vehicle, there are no other machines here. Infantry have to do everything here. The fight takes place in a small town, with a monastery located at the top of the hill - that's where the last pair of crates is located.
The whole town is built on the slope of that hill. The attackers - by destroying the gold crates - go higher and higher, and finally they reach the monastery mentioned above. That kind of terrain geometry creates a lot of vantage points located on the highest floors of the buildings. What is more, the structures are standing close to each one, so You can not only watch the crates from the windows, but also all the routes leading to them.
It is worth noticing that the crates and their defenders often cannot be attacked from behind. Frontal assaults and flanking are the only tactical propositions here.
The defenders' team have some machine guns emplacements here, but they're becoming useful quite rarely. In the chaos of war, the shooter sometimes may not notice enemies coming from the flank or the snipers trying to take him out with a single shot through the hole in his shield.
The most common plays
First of all, check what You can see from the windows of buildings standing in the vicinity of gold crates. Some of them provide great cover and a nice defensive position.
Because the are no vehicles worth marking with the laser designator, and the distances are here quite short, the Recon class is nearly useless on this map. Most of the players pick the Assault class (always with M16 assault rifle!), Support (for healing and huge clips) and the Specialist (for extremely high rate of fire of his primary weapon).
However, there is one place designated just for sniper - the monastery's windows, from which You can see the town and the attackers coming towards the last pair of gold crates.
The whole city is like one big vantage point.
The attackers - in search for the best way to the gold crates - should walk through every building on their way. Most of the houses on the map are placed in a specific way, so they can easily enter the structures through one door and get out through another (located near the defenders). Sometimes it is possible to get through a series of buildings, which not only allows to get close to the crates without being spotted, but also protects from the artillery strikes.
