Gameplay
In survival mode the levels often have a protected spawn with lockable doors, but in certain levels the doors cannot be locked. Some levels have no protected areas, thus leaving little time to buy and consider different weapons or items. Part of the difficulty of survival is that if the player doesn't act fairly quickly and often the enemies can build up and become virtually impossible to kill without being overwhelmed. A good solution to this is to toss some form of grenade or other throwable into the cluster and/or use an fully automatic or area-of-effect damage weapon.

Loot
Killing enemies and accessing hard to reach locations i.e. the top of a tower, results in the player gaining loot. After acquiring it, players can convert all the loot collected from killing enemies to Volts at the Volt Converter.

This will also increase your score.

Buying Items
You can buy items with the Volts you collect to help you survive the increasingly difficult waves. There are various upgrades for each weapon, such as extended magazines and scopes. Additionally, a Nano shower can be used to repair the player at a cost of 5 Volts (by default).

Some levels are based on going back to the main hub where you spawn to purchase items, while others are more based on getting to specific areas in the map to get more advanced weapons and items. Some of these areas can be guarded or difficult to access.
