This is an idea I thought would be great for Escalation mode. I often find that after so many waves, the game can start to become boring and frustrating, especially when the enemies get tougher and you find yourself buying ammo as often as you're actually shooting. Upgradable weapons would add a further level of depth and excitement to the game, and give you something to do with all those extra points besides buying Overshields. Upgrading is simple - just buy a duplicate of a weapon you already have, and rather than simply get an ammo refill, the weapon is upgraded another level: Level 1: Standard weapon Level 2: 25% extra ammo Level 3: 25% extra magazine capacity Level 4: 25% extra damage Level 5: Special (varies depending on weapon) Photon Burst Rifle > Full Auto: Becomes a rapid fire weapon - simply hold the trigger to unleash a stream of bullets EMP Shotgun > Thundershock Shells: Increases weapon damage by a further 75% - yep, double damage! Energon Battle Pistol > Cerebro Lock: Automatically targets enemies heads when Fine Aim is used. Scatter Blaster > Blaze Away: Increases magazine capacity by a further 75%. Null Ray > Rail Gun: Reveal enemy locations ALA Orbital Beacon whenever Fine Aim is used. In addition, can now fire through walls and scenery. Plasma Cannon > Nucleon Charge: Adds a forth charge level to the cannon whereby the signal lights change red, before unleashing a Nucleon Shot. Thermo Rocket Launcher > Omni Lock: Can now lock onto Robot modes aswell as vehicles - in addition, four lock ons can be achieved simultaneously, providing all targets are in sight at the same time. Magma Frag Launcher > Magma-tism: Increases the 'stick' radius of the mines threefold, giving them an almost homing effect Scrapmaker > Hypershot: Weapon starts firing at its previous maximum firing speed, increasing to DOUBLE its rate of fire. Extremely powerful, but also eats up your ammo. Energon Repair Ray > Healing Touch: Fully recharges allies health with a single shot - sounds overpowered? Well, you HAVE just spent nearly 6000 points on it.
