When brainstorming concepts for gears of war 3, Epic had a long list of improvements it wanted to integrate: make the biggest single-player campaign in series history, expand the co-op to include four players, fix the party matchmaking in multi-player, and build a new multi-player mode where players can become the locust horde to fight against marcus and dom. Though it was undoubtedly the most popular addition to gears of war 2, Horde mode also recieved a revamp. Since Horde mode was introduced in 2008, the cooperative competition that pits a team of players against increasingly more difficult waves of enemies has become ubiquitous in shooters, appearing in a wide range of franchises including blockbusters like halo (re-branded as firefight mode), call of duty (zombie mode), and uncharted (siege mode). To stay ahead of the pack, Epic knew it needed to step up it;s game Horde 2.0 preserves the primary mode construct - you're still squaring off against 50 waves of baddies - but adds a currency system, boss fights, and elements of tower defense to the mix.
By killing enemies and helping teammates the players earn cash to spend on ammo, new weapons, reviving down teammates, or a new array of defensive deployments. Such as barriers, manned turrets, sentry guns, and decoys. Each of which have four tiers, For example the first level barrier is a spiked wall. If you upgrade it to the top tier it becomes a devastating laser fence. Mother teresa types can also gift money if a mate is running low on cash and ammo, and organised teams can pool together to get the more expensive toys such as the silverback which has dual chainguns and rocket launchers.
